Question

Quizplus · Accepted Answer

When heat is added or pressure is reduced, the kinetic energy of the particles in the liquid increases, causing them to move faster and with greater force. This results in the molecules breaking free from the cohesive forces of the liquid and entering the gas phase. Therefore, an increase in heat or a decrease in pressure will cause a liquid to change into a gas.
