Question 1

What is the compressibility and density of a solid?

Answer 1

Solids can’t easily be compressed and are very dense.
they are very dense as there is a lot of particles in a small volume.

Question 2

What is the compressibility and density of a liquid?

Answer 2

Liquids can’t be easily compressed because it is quite dense. So there are quite a lot of particles in a small volume.

Question 3

What is the compressibility and density of a gas?

Answer 3

Gasses can be easily compressed because it is not dense and the particles move to fill the shape ,so there are not many particles in a large volume.

Question 4

Through what processes is energy supplied when changing from one state to another?

Answer 4

Melting, boiling and subliming (changing from solid to gas)

Question 5

Through what processes is energy given out when changing from one state to another?

Answer 5

freezing, condensing and subliming. ( changing from gas to solid)
