Q

What is the name of the change from gas to liquid?

Is the energy increasing or decreasing?

A

Condensation

Decreasing

17
Q

What is the name of the change from liquid to solid?

Is the energy increasing or decreasing?

A

Freezing

Decreasing

18
Q

What is the name of the change from solid directly to gas?

Is the energy increasing or decreasing?

A

Sublimation

Increasing very quickly

19
Q

How does increasing temperature affect the particles?

A

When temperature is increased, so is the energy of the particles. This causes the particles move faster are further away from each other

20
Q

Is the change of state reversible?

A

Yes, because they are only physical changes

21
Q

Why does the temperature stay constant as the substance is changing state?

A

When reaching the temperature at which it changes state, the temperature remains constant until all the particles of the substance have the same amount of energy. For example, when a solid has reached its melting point, the temperature of the solid remains constant until all of it have become a liquid, only then will it move on to becoming a gas
