Interpretation:
The process of evaporation and condensation is to be described and which process requires the input energy is to be predicted.
Concept introduction:
Evaporation is process, in which liquid change its physical state to gas and condensation is the change of the physical
Answer to Problem 24A
The evaporation is the conversion of liquid to gas physical state of substance and condensation is the conversion of gas to liquid physical state of substance. The Evaporation requires energy to overcome the intermolecular forces in substance.
Explanation of Solution
In the evaporation process, liquid molecules escape the surface of liquid and form as a gas or vapor. This required energy to overcome the intermolecular forces of the liquid. The average kinetic energy of the substance overcome the intermolecular force of the liquid, the molecule are goes in vapor state.
The condensation which gas molecule converts to liquids phase; it is reverse process of evaporation. It releases the energy during condensed the vapor to liquid.
The evaporation and condensation are opposite process of each other and evaporation required input energy, while condensation releases the energy.
