When a gas changes into a liquid, it is called and the speed of the molecules is

Explanation:

Condensation is defined as the process in which gaseous state of a substance changes into liquid state.

As it is known that in gaseous state, molecules are held by Vander waal forces due to which they have high kinetic energy.

In liquids, molecules are held by slightly strong intermolecular forces of attraction as compared to gases. Hence, molecules of a liquid are able to slight past each other.

Hence, they have definite volume but no definite shape. So, liquid molecules have less energy than gaseous gases.

Thus, we can conclude that when a gas changes into a liquid, it is called condensation, and the speed of the molecules is slower.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.

the dissolution of polymer can be thermodynamically described in 2 steps.
