Question

condensation: gas to liquid

1. the change of state from a gas to a liquid is called
2. at a given pressure, the condensation point for a substance is the same as

Explanation:

1. The term for the change of state from gas to liquid is condensation as stated in the given text.
2. At a given pressure, the condensation point of a substance is equal to its boiling - point. This is because the process of going from gas to liquid (condensation) and from liquid to gas (boiling) are opposite phase - change processes and occur at the same temperature for a given pressure.

Answer:

1. condensation
2. its boiling - point
