Question

State whether true or false.
The land and sea breezes are based on the fact that the specific heat of vaporization of steam is very high.
A. True
B. False

Answer 1

It is based on the heat which is required to turn one gram of a liquid into its corresponding amount of vapor. It is similar to that of ice which is at zero degree and melts to form water at the same temperature.

Complete answer:
We are given a situation in which the land and sea breezes are based on the fact that the specific heat of vaporization of steam is very high. The statement is valid. Water's specific heat capacity is much greater than that of sand. During the day the air above ground becomes colder than water. So cold air blows to land known as the sea breeze over water or sea and vice versa for the land breeze. Hence, it’s true.

The correct option is A.

Additional information:
Heat of vaporization of water: Much as it takes a lot of heat to boost the temperature of liquid water, it also takes an extraordinary amount of heat to vaporize a given amount of water, since in order for the molecules to fly off as gas, hydrogen bonds must be broken. That is, water has a high vaporization heat, the amount of energy required at a constant temperature to convert one gram of a liquid substance to a gas.

Note: Vaporization heat is defined as the quantity of heat required to transform $1\,{\text{g}}$ of liquid into vapor without raising the temperature of the liquid. A substance's high specific heat means that a significant quantity of heat is needed to increase the substance's temperature. Water occupies approximately $70\%$ of the surface of the Planet and its high specific heat plays a very important function as it is capable of absorbing a lot of heat without a major temperature increase.
