Question

a student is doing a lab where they take a gaseous substance and turn it into a liquid substance. what happens to the potential and kinetic energies of the particles? a potential decreases, kinetic decreases b potential increases, kinetic increases c potential increases, kinetic decreases d potential decreases, kinetic increases

Explanation:

When a substance condenses from gas to liquid, the particles get closer together. Inter - molecular forces increase. Potential energy associated with the intermolecular forces decreases as the particles come closer. Also, the temperature of the substance decreases during condensation which means the average kinetic energy of the particles decreases.

Answer:

A. Potential decreases, Kinetic decreases
