Question

What happens to the volume of the substance when the temperature increases?

Answer 1

Understanding the concept:

• Volume, as we are all aware, is the amount of three-dimensional space that is physically confined by a closed surface.
• Consider the area or form that a substance, such as a solid, liquid, gas, or plasma, occupies.
• Its S.I.unit is a cubic meter (${\mathrm{m}}^3$).

Explanation of volume of substance by increasing temperature:

• When a substance's temperature rises, its molecules begin to move randomly in all directions, expanding and increasing in volume.
