When the kinetic energy of the particles in a metal is decreased, the metal generally contracts. As the kinetic energy decreases, the particles move less vigorously, leading to a reduction in the average distance between them. This results in a contraction of the material.
What happens to some metals when the kinetic energy of their particles is decreased? (1 point)
• They conduct.
• They melt.
• They contract.
• They expand.
