Essential Chemistry for IGCSE - Particles And Purification (Section 3 - No. 50)
What happens to the kinetic energy of particles during a phase change?
Kinetic energy increases.
Kinetic energy decreases.
Kinetic energy remains constant.
Kinetic energy fluctuates randomly.
Explanation
During a phase change, the kinetic energy (temperature) remains constant as the energy is used to overcome intermolecular forces.
