Solution

Solution Steps

Step 1: Understanding Vapor Pressure

Vapor pressure is the pressure exerted by a vapor in equilibrium with its liquid or solid phase. It is dependent on temperature; as temperature increases, the kinetic energy of the molecules increases, leading to more molecules escaping into the vapor phase.

Step 2: Analyzing the Effect of Temperature on Vapor Pressure

When the temperature of a liquid is increased, the molecules have more energy to escape from the liquid phase into the vapor phase. This results in an increase in the number of molecules in the vapor phase, thereby increasing the vapor pressure.
