Question

Name the following. Expansion of a substance due to heat.​

Answer 1

Answer:

When a substance is heated, its molecular movement increases. Due to this, the average distance between the molecules also increases, thereby increasing the volume of the substance, i.e., expanding the substance. ... Molecules of gases have no bonding at all; therefore, gases expand the most among the three.

Answer 2

Thermal expansion :

=>Linear expansion

=>area expansion

=>cubic/volume expansion
