Question

11. When a metal such as copper is heated it
extends. What happens to the particles
when a solid is heated?​

Answer 1

Answer:

When a metal is heated the kinetic energy in the particles increases and hence the force pf attraction decreases among the particle (as electrons try to escape due to kinetic energy). This causes the metal to expand.

Answer 2

Answer:When a metal is heated the kinetic energy in the particles increases and hence the force pf attraction decreases among the particle (as electrons try to escape due to kinetic energy). This causes the metal to expand.
