Question
The latent heat of vaporization has the effect of cooling a liquid because ________.
when something becomes a gas it releases heat, and the liquid gets cooler as a result
a solid absorbs heat from the atmosphere when it becomes vapor
the liquid that forms the gas molecules absorbs and stores heat until all of the liquid becomes a gas
the gas molecules that form and leave the liquid are the higher temperature molecules in the liquid, so the temperature of the liquid is reduced
none of the above

Explanation / Answer
The concept can be Understand by the help of Newton cooling effect. It was stated that when the substance absorbed energy from a body they make the host body cool and escaped. Due To their absorption of energy the host body feels cool.
Now in this question it was found about the latent heat of vaporization. The latent heat can be understands or take it as the internal energy Which get the energy by absorbing from the surrounding. So it can be defined as the heat required to change one mole of liquid at it's boiling point under standard atmospheric pressure.
So the correct answer is a solid absorbs heat from the atmosphere when it becomes vapour and hence make cooling.
So option B is correct.
