Hi Children!
I'm so glad that you have made your way to this blog to attempt on this week's challenge.
Now that we have learnt about the effects of heat on things around us; solid, liquid and gas, I will need you to think and answer the following questions:
1) How is heat used in real life? Quote at least 2 examples.
2) Briefly explain how they work.
In your answers, you might want to use the following words:
gain/lost/contract/expand/heat
3) Comment meaningfully on at least 2 of your friends' comments.
Remember to build on each other's knowledge rather than to give a "correct" or "wrong" reply if possible.
Have fun!
Mr Ang
we use heat to survive.
ReplyDeleteAmihr I think your right but how do you use heat to survive.
DeleteAnirudh
Yes Amir,
DeleteHow to use heat to survive?Be more eleborate,ok?Give some examples,like inwhat way do we use heat.
xoxo,
Pashea
Is That all?
ReplyDeleteYou Can go to this website http://www.scienceinschool.org/2012/issue24/energy
ReplyDeletesun and fire (gas). sun as to drying up cloths and fire as to cook food.
ReplyDeleteMaybe you can use the dryer too. Electricity converts to heat energy to dry up the clothes.
DeleteIt is often used to heat homes and factories directly, and it is often used in the chemical industry and oil refineries to make processes work
ReplyDeleteAnother big use of heat energy is in generating electricity in power plants
Dear Khaliesah,
DeleteYes it is often used to heat homes but in which area.Like is it used for warming yourself,cooking ect.Btw, Wishing you a happy holiday!:)
Best Wishes,
Pashea
(P.S.What is your handphone number?Whatsapp me,you have my phone number right?:))
heat can be used to cook things.
ReplyDeleteDear Wan Yu,
DeleteI think you are right because heat can be use to cook things.
Ithink so too.
DeleteThis is the website for question 1..... http://www.scienceclarified.com/everyday/Real-Life-Physics-Vol-2/Heat-Real-life-applications.html
ReplyDeleteIt can explode explosive I have something wrong with my computer
ReplyDeleteheat can also generate energy.
ReplyDeleteit is the heat from the sun that dry our cloths.
DeleteNo,it is solar power.
DeleteHeat can melt things burn things and more
ReplyDeletewhat do heat melt?
Deletewenkang
Wen Kang heat can melt candle(wax) , butter and many more!
DeleteWe use heat for cooking, ironing clothes, and to keep us warm.
ReplyDeletewenkang
In cold countries,people use warmers to keep them warm.
DeleteWe also can use heat to keep us warm. We also can use heat to melt things
ReplyDeleteI think you are correct.
DeleteHeat can be used for cooking and burning ashes.The pot will gain heat from the flames ond fry the food while fire is used to burn the dead body into ashes.
ReplyDeleteVery disgusting
DeleteIt is true,isn't it?
DeleteI read that cremation is happening to reduce dead body.
DeleteSorry,I meant saw not read.
DeleteDear friend,
ReplyDeleteWe can use heat to heat things up because the things will gain heat and I could use heat to cook too.
Heat can kill!!
ReplyDeleteEven though heat can kill, we will also die without heat.
DeleteDear friends,

Heat can be cooking.
ReplyDeleteSebastian
We need heat to cook and make us warm.Without heat we will eat raw food and might freeze to death so heat is important. From Xavier

ReplyDeletehttp://viviankueh-physicsproject2009.blogspot.sg/2009/07/1-conduction-in-real-life.html
we cook thing using heat by stove.
ReplyDeleteHeat is usefull for our everyday life as it cooks raw meat and fish for us to eat and to make us the water heater
ReplyDeleteDEar class,
ReplyDeleteI think we use heat to heat up and melt things.
Wu Rui
Heat is also used for energy. Example, Solar Energy.
ReplyDeleteit gives us enerrgyy and warmth.
ReplyDeleteit heat us.
From zheng heng
You can google kids korner, research on heat. :)
ReplyDeleteOps!
ReplyDeleteStacey!!!!!!!!!!!!!!
ReplyDeleteThey work like sun loeses heat to the clothes as they are wet it gains heat and evaperates.for fire it makes food cooked.
ReplyDeleteheat is needed a lot in our daily lives. Why is heat important? Heat is important because it is an invisible substance that keeps us warm. Heat appears in many things like fire. Heat is also necessary when you are cooking a specific dish in the oven, microwave or stove.
ReplyDeleteAnirudh
Heat can be used to craft sword and shield and obviously spear
ReplyDeleteI agree with Wan Yu.
ReplyDeleteThe process of converting a heat source into electrical current can vary depending on what type of energy source and conversion method is used.

Heat is use to.....
ReplyDelete1)cook things
2)dry things like clothes etc.
All forms of matter, from a cold slab of marble to your own skin, have some temperature. Different materials conduct heat in different ways, but heat will always flow from the hotter material to the colder material
ReplyDeleteLiesah
Are you Khaliesah?
DeleteSo we can shape stuff and cook stuff
ReplyDeleteWuRui
How,I don't understand?
Deleteheat can do this see it at this web http://www.todayszaman.com/news-304431-man-killed-as-fires-rage-across-southern-australia-heat-wave-adds-to-woes.html
ReplyDeleteCharlotte,what are u talking about?
ReplyDeleteplease reply. P.S.from zheng heng
Without heat we can perish.
ReplyDeleteanirudh,you spelt my name wrongly(amir)
ReplyDeleteThe heat and light produced by the sun provide an enormous source of energy. A number of technologies, such as photovoltaic (PV) cells, have been developed to harness this energy so it can be used as a power source for generating electricity and heat (solar heating).
ReplyDeleteDear friends,
ReplyDeleteWe use heat all over the world. Heat is used to cook, heat water, in factories, to give warmth and can convert the light from the sun to solar energy.
Heat in real life is used to make us feel warmer.It is sometimes used in experiments to make metals,plastics and even paper.I'll find out more about heat and reply again.
ReplyDeleteWe used heat to boil water
ReplyDeletedear class,

hi sanjith
ReplyDeletedear class
ReplyDeleteheat is used for cooking food and keeping us warm.the food gain heat from the fire under the wok.the air in the room gain heat from heater.
Heat used in real life can be used like a jacket. A jackets warmth can flow into the body so the person wearing the jacket can feel their body getting warm.The coldness of the body can go to the jacket.Heat will flow from hotter objects to colder objects until both are at the same tempereture.
ReplyDeleteFrom,Cheryl
I think your right but when I went to google and searched it said that the jacket will trap your body heat to keep you warm.
DeleteAnirudh
1) Thermal and heating phenomena are part of the physical phenomena which we meet in our daily lives.
ReplyDeleteAll forms of matter, from a cold slab of marble to your own skin, have some temperature. Different materials conduct heat in different ways, but heat will always flow from the hotter place to the colder place.

We use heat to keep ourselves warm whenever we are feeling cold. This is because we use fire to keep ourselevs warm and the fire is a heat source. The fire will lose heat to our body and our body gains heat from the fire. That's why we feel warm when we are near fire and many other heat sources.
ReplyDeletecry
ReplyDeletedear class, heat is used for cooking food and keeping us warm.the food gain heat from the fire under the wok.the air in the room gain heat from heater
ReplyDeleteHellooooooooooooooooooooooooooooooooooooooo!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Who are you seriously?
Deleteit's wu rui.
Deletesamiha
Ooh!!!
Deleteheat is often used to heat homes and factories directly,heat is often used in chemical industry and oil refineries to make processes work another big use of heat is in generating electricity in power plants
ReplyDeleteHeat is a form of energy that is transferred by a difference in temperature.Different materials conduct heat in different ways, but heat will always flow from the hotter material to the colder material.
ReplyDeleteAnirudh
I think that you are correct ,Pi Juan that was one of the answer I found while I was on google
ReplyDeleteI agree with you Xavier we can't eat RAW food all the time
ReplyDeleteHave you ever wondered how a jacket keeps you warm? This is how!
ReplyDeleteA jacket works by using your body heat to warm you. The jacket acts as a trap to keep in warmth.
Anirudh
Anirudh I agree with you.
ReplyDeleteDear friends,
ReplyDeleteHeat is widely used around the world. It is used in houses, in industries and many more. Example, at home, heat from the sun is used to dry clothes and to preserve food. Heat from electricity is used to iron clothes, for water heater and to bake or toast. Heat from burning fuels is used to cook food and boil water. Heat is used in industries as well to generate electricity in a power plant, to melt, shape, cut and harden metals and to process food, glass, paper and textiles.
Rub your hands together fast. Feel the heat? That’s friction. It’s the resistance to movement of one object – your hand -- by the other object – your other hand. In the process, kinetic energy changes into heat energy. The more resistance there is, the more friction produced. More friction means more heat. A polished surface, like a gym floor or a lane in a bowling alley, reduces friction. That’s why a bowling ball rolls fast down the lane towards the pins. (As long as your aim is good!) If the alley was covered in carpet, there would be more friction. The ball would slow and wobble and could even stop partway to its destination.
The engines in our cars and trucks create heat too.
For wider scale transportation, steam engines power locomotives and steamships. Within a steam engine, water is heated by burning coal, wood, or oil. The heated water turns to steam. Steam moves a piston or blade, which turns a wheel. In this way, a steam engine uses heat and turns it into work.
I agree with you Sanjith.
DeleteAnirudh
I don't really understand the part about the car ?
DeletePlease reply!Thanks a lot.
DeleteHeat is a Form of Energy
ReplyDeleteAll forms of matter, from a cold slab of marble to your own skin, have some temperature. Different materials conduct heat in different ways, but heat will always flow from the hotter material to the colder material. Take the example of an aluminum can and a Styrofoam cup. Your body temperature is hotter (usually) than both of those objects. If you hold one in each hand the heat from your hands transfers to the can and the cup. Because aluminum conducts heat better it will transfer the heat throughout the can. Styrofoam is not a good conductor, so the heat stays mainly where your hand is touching the cup. The can feels cooler, but that is only because the heat has been transferred to the entire can.
Anirudh
Solar Energy
ReplyDeleteHeat can be created in many ways, but the most basic, natural form is solar heat. Solar energy is just that; heat produced by the sun and absorbed by other materials. Dark-colored objects absorb light and heat faster than light-colored objects. Dark objects also store heat longer. Light-colored objects appear lighter because they are reflecting most of the solar heat away rather than absorbing it. For this reason solar panels used to create electricity are black

1.Iron and Gas stove.
ReplyDelete2.Electricity gives energy to the iron so that it gains heat to iron our clothes. The gas in the gas stove converts to heat energy to cook our food.
To my friends,
ReplyDeleteheat is energy transferred from one body to another and so on by thermal reactions.
Thank you for all your ideas, Guys & Girls!
