A

Condesation

19
Q

Solid to gas

A

Sublimation

20
Q

What happens when a solid is heated?

A

The particles vibrate faster and faster untill they break away from eavh other. Then the solid has melted to a liquid

21
Q

What happens when you turn liquid to gas?

A

The particles are heated more so get more energy and move faster. The faster ones break away from each other and the liquid turns into gas.

22
Q

When changing state what happens?

A

They need energy to overcome the forces of attraction between the particles in the orgianl state.
