Question

The process in which a substance changes from a gaseous state to the liquid state is

A. critical temperature.
B. absolute zero.
C. evaporation.
D. condensation.

Answer 1

By definition we have to:

In physics, condensation is a change of state by which a substance passes from a gaseous state to a liquid state.

For example, in a refrigeration cycle, the refrigerant leaves the compressor in the gaseous state, from here, it enters the condenser, a state change called condensation occurs and the refrigerant leaves in liquid form. This process is useful in air conditioners.

Answer:

The process in which a substance changes from a gaseous state to the liquid state is:

D. condensation.

Answer 2

This process is called D. Condensation.

You can easily notice this happen on Air conditioning devices, where the cold gaseous air is turned into water that drips from the air conditioning unit due to condensation.
