False
2 of 14
Diffusion happens in gases and liquids. True or false
True
3 of 14
What practical did we do that represented Diffusion?
Tea bag practical
4 of 14
The volume of solids cannot be changed. True or false?
True
5 of 14
Liquids can be squashed. True or false?
False
6 of 14
Gases have a fixed volume. True or false?
False
7 of 14
Gases are less dense (heavy) than solids and liquids. True or false?
True
8 of 14
The change from solid to liquid is called melting. True or false?
True
9 of 14
The change from gas to liquid is called condensation?
False

If a material gets cold, the particles expand. True or false?
False
11 of 14
The air pressure is affected by temperature and particles quantity. True or false?
True
12 of 14
If a balloon is crinkled means that have high pressure inside. True or false?
False
13 of 14
If you took a bag of crisps on a plane, after take off what would of happened to the bag?
As you take off you are going into less pressure atmosphere. Less pressure on the outside of the bag means there is more pressure on the inside relative to the outside, so the bag expands.
