Based on your understanding of the relationship among thermal energy and particle motion, kinetic energy, density, temperature, and thermal expansion and contraction, work in groups to develop a model that demonstrates how all these changes occur when thermal energy is added to a substance.​



Answer :

The addition of thermal energy leads to the thermal expansion of a body.

What is thermal energy?

We know that the particles of matter are in constant random motion. This is one of the postulates of the kinetic theory of matter. The kinetic energy of the particles that compose matter is directly proportional to the temperature of the body.

Hence, as the temperature of the body increases, the kinetic energy of the particles that are in the body increases. The addition of heat implies that the temperature increases. Heat is a form of energy thus the addition of heat means that thermal energy is added to the body.

One of the effects of heat is that it causes a body to expand. Thus the addition of thermal energy leads to the thermal expansion of a body.
