Question

when a metal such as copper is heated it expands.explain what happens to the metal particles as the solid metal expands?​

Answer 1

Explanation:

when a metal such as copper is heated the metal expands because of kinetic energy the particles loose the force of attraction and this expand

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.

I hope my answer helps you.

Answer 2

The vibration of the particles becomes higher, which results in an increase

in size.
