Question

4. The following occurs when heat energy is removed: Gas --A-> Liquid-B--> Solid.
What would be the phase change for A and B respectively?
A. Condensation, freezing
C. Condensation, melting
B. Melting, evaporation
D. Sublimation, deposition​

Answer 1

Answer: The phase change for A and B respectively is condensation, freezing.

Explanation:

A process in which gaseous state of a substance converts into liquid state is called condensation.

For example, conversion of steam into water.

A process in which liquid state of a substance converts into solid state is called freezing.

For example, conversion of liquid water into ice.

Thus, we can conclude that the phase change for A and B respectively is condensation and freezing.

Answer 2

Condensation and freezing would be the phase change for A and B respectively.

What is Freezing?

This is the process in which a liquid becomes solid and is mostly caused by exposure to cool temperatures.

Gaseous substances also have the ability to become liquids through the process known as Condensation. This therefore makes option A the most appropriate choice.
