The Vapor Pressure of a Liquid Increases with Increasing Temperature

Multiple Choice

The vapor pressure of a liquid increases with increasing temperature.Which of the following statements best explains this relationship?

A) All the molecules have greater kinetic energies.
B) The number of gaseous molecules above the liquid remains constant,but these molecules have greater average kinetic energy.
C) The faster-moving molecules in the liquid exert a greater pressure.
D) The intermolecular forces between the molecules decrease at higher temperatures.
E) The average kinetic energy of molecules is greater; thus more molecules can enter the gaseous state.
