Q

What is a solid?

A

Something with a fixed shape and volume

17
Q

What is a liquid?

A

Something with a fixed volume but no fixed shape

18
Q

What is a gas?

A

Something that does not have a fixed shape or volume, easy to squash

19
Q

What is a melting point?

A

The temperature at which a substance changes from the solid state to liquid state when heated

20
Q

What is the boiling point?

A

The temperature at which a liquid boils

21
Q

What is the freezing point?

A

The temperature at which a substance stats to turn from a liquid into a solid

22
Q

What is the condensing point?

A

The temperature at which a gas turns into a liquid

23
Q

What are state changes?

A

They are physical changes, the chemical properties of the substance do not change. This is because the particles themselves do not change - only their arrangement, movement and amount of stored energy
