Chapter 17, Problem 7RQ

What is it called when evaporation occurs beneath the surface of a liquid?

To determine

The name of the process when evaporation occurs beneath the surface of a liquid.

Answer to Problem 7RQ

When evaporation occurs beneath the surface of a liquid, it is called boiling.

Explanation of Solution

The transformations of matter are of two types. The types are physical change and chemical change. The physical change includes the change of states of matter.

There are three states of matter. The states are solid, liquid, and gas. The different states are due to the difference in the movement of molecules that are present in matter.

The states change when the heat is applied or removed.

Evaporation is a process in which liquid turns into a gas. It takes place at the surface of liquid initially.

When the temperature rises enough the evaporation takes place beneath the surface of the liquid. It gives rise to bubbles and they are buoyed up to the surface. This process is known as boiling.

Conclusion:

Therefore, when evaporation occurs beneath the surface of a liquid, it is called boiling.
