The physical process of evaporation

The physical process of evaporation involves (1) addition of heat energy and (2) increase in entropy

Explanation:

During evaporation, liquid molecules convert into gas molecules. As gas molecules has negligible intermolecular force as compared to liquid molecules therefore heat energy has to be applied to separate liquid molecules by breaking intermolecular force and convert them into gas

Again, gas molecules are free to move. Hence they possesses more degrees of freedom. Therefore gas molecules have higher entropy than liquid molecules. So entropy increases during evaporation.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
