Question

When a substance is heated kinetic energy of particles decreases.

• A. True
• B. False

Answer 1

The correct option is B False

Theoretically, heating a solid to higher and higher temperatures changes its phase to a liquid, and finally to a gas.
A solid consists of low kinetic energy vibrating particles locked into position by interparticle attractive forces. When heat is applied, energy is absorbed and the particles start vibrating more vigorously.
