when air is hot it expands when its cold it contracts .

# data[].attributes.body
when it gets hotter the volum expands and when it gets cold it compresses

# data[].attributes.body
When it is heated, it will rise. When it is cooled, it stays the same.

I predict that when a volume of air is heated it will expand. When a volume of air is cooled it will contract.

# data[].attributes.body
Heated:It will rise
Cooled:It may settle

i think what happens is that when its heated the gas expands and rises up.

# data[].attributes.body
when you use hot air it goes up and expands when cold and and went down.

# data[].attributes.body
when air gets heating it will expand and take up more space but when it's cooled it will take up way less space.

# data[].attributes.body
I think that when the air gets heated it will start to expand, and when the air gets cooled it will start to contract.

# data[].attributes.body
I think when air is heated it will expand and when air is cold it contract.

# data[].attributes.body
When the air is heated it becomes lighter and bigger. Cold air get smaller and is heavier. Hot expands, cold compresses.

# data[].attributes.body
when the air is heated rises but when air is cooled down it will contract

# data[].attributes.body
when heated it will expaned.When cools in will go down.

# data[].attributes.body
I think that when air is heated it will get bigger, this is called expansion. I think that when cooled, air will get smaller, this is called compression.

# data[].attributes.body
I think when air is heated the particles go farther apart and expand. When cooled they get smaller and closer together.

# data[].attributes.body
When the air is heated it will expand and when its cooled it will contract.

# data[].attributes.body
When the air is heated air rises and when air is cooled it starts to move slower and lower down.

# data[].attributes.body
When the gets heated it expands so it will get super compressed you will not be able to push it down.Now if the air was cold it would be like pushing normal air room temperature.

# data[].attributes.body
When air is heated it will expand. When air is cooled the volume will contract.

# data[].attributes.body
I think that when the air is heated it will expand and when the air is cooled it will compress.

# data[].attributes.body
I predicted the complete opposite of what really did happen. I honestly thought that when it was hot air, it ould contract and when cold air, it would expand.

# data[].attributes.body
when the air is heated it will expand when it is cooles it will contract

# data[].attributes.body
When the air is heated, it will expand, and take up more space. When the air is cooled, it will contract and be smaller.

# data[].attributes.body
I predict that when a volume of air is heated, the air.......
This is called: expansion of air.

I also predict that when a volume of air is cooled, the air......
This is called: contraction of
air.

When the air inside a balloon is heated, the air will expand and take up more space. When it is cooled, it will contract and be smaller.

# data[].attributes.body
When air inside a balloon is heated it expands when it is cooled it contracts.

# data[].attributes.body
When air is heated a ballon will expand, but when a balloon is cooled a the air with compact.

# data[].attributes.body
The air will rise and expand when it is heated. The air will compressed and it will not rise like when it was heated.

# data[].attributes.body
If the air is heated it will rise, and expand, if the air is cold, then the air will be compressed

# data[].attributes.body
I predict when the air is heated it will start to expand and when the air is cold it will contract. For example when we watch the video of the balloon, when it got heated it gained air and when it was cooled is lose air.

# data[].attributes.body
I think that when the air is hot the balloon will start to expand but when its cold it will start to contract and lose air.

# data[].attributes.body
I think that when the air is heated it will get bigger. This is called expansion.I think when cooled it will get smaller .This is called compression.

# data[].attributes.body
When the balloon is in the cold water it wouldn't get air in the balloon and when it is place in the hot water it has air in it and float.

# data[].attributes.body
I predict that the air will expand when heated which will eventually cool down which means it will gradually contract which means it will become smaller.

# data[].attributes.body
I predict that the volume of the air will expand when it is heated. When the air is cooled, its volume contracts. The heated air will fill up the bottle, but the cooled air will just go around, not filling the balloon.

# data[].attributes.body
I predict that when air is heated it will expand also know as the expansion of air and when air is cooled it will contract also known as contraction of air.

# data[].attributes.body
I predict that when it goes up that the water get to room temperature that it could expand a little.

# data[].attributes.body
I predict that when a volume of air is heated, the air will expand. That is called; expansion of air. I think when the air is cooled it will contract back in. That is called contraction of air.

# data[].attributes.body
I predict that when the heated one will expand and the cooled one will compress.

# data[].attributes.body
I presict that the air will exspand when heated. If you have seen like a cake or something that needs too be heated to rise you know when the cake bakes it rises and exspands. Then when it is cooled it will decrease a bit but not a lot because it is cooling down and leting the air presure flow .

# data[].attributes.body
I predict that when air is heated, it will expand. I already know that hot air rises, I think that is why in the video we watched on Discovery Education had the balloon filled with hot air expand and the balloon filled with cool air deflated or compressed.

# data[].attributes.body
I think it will fog up inside because of the hot air and cold air. The cold air will expand because that's what cold air does.

# data[].attributes.body
i think when the air is heated it will compress into t he coke bottle. When it goes into the cold water the air expands and the can is crushed.

# data[].attributes.body
I think the volume of the air will expand and when it is cooled it is contracted. The video of the can shows that when the can was hot it was normal but when the can got put in cold water it crushed.

# data[].attributes.body
It might go up and down like with different amounts of people in the room or at that place.

# data[].attributes.body
I predict that when a volume of air is heated, the air will expand. The is called expansion of air. I also predict that when a volume of air is cooled, the air contracts. This is called contraction of air.

# data[].attributes.body
I predict that when the air is heated up I think it will expand and when cool down it will contract.

# data[].attributes.body
When a volume of air is heated the distance between the particles will increase or expand. When a volume of air is cooled the distance between the particles decreases and the air is compressed.

# data[].attributes.body
When a volume of air is heated the air will expand.
This is called: expansion of the air
Expansion means the air is pushed out ward to take up the space we’re force was. So when air gets hot it expands to take up lost space.
When air is cooled it will contract
This is called: contraction of air
Contraction means a gas is reduced or pulled together when cooled. So when air is cooled it contracts .

# data[].attributes.body
When air is heated I think the volume of it will expand.
This is called: expansion of air
Expansion means when the force is removed air expands to take up more space. This tells me that when the air gets hot it expands to take up more room.
I think when the air is cooled the volume will contract.
This is called: contraction of air.
Contraction means the reduction of air when cooled. This tells me when the air gets cold it contracts.

# data[].attributes.body
I predict that when a volume of air is heated, the air.......
This is called: ________of air.

I also predict that when a volume of air is cooled, the air......
This is called:  ________of
air.
