is the process when matter changes form a solid directly to a gas state

18
Q

Describe Evaporation

A

is the change of state from the liquid state to the gas state

19

A

is the change of state form solid to a liquid

20
Q

Describe Condensation

A

is the change of state from a gas to a liquid

21
