Question

When a gas is heated its temperature increases. Explain this phenomenon based on kinetic theory of gases.

✓

Answer

Molecules of a gas are in a state of continuous random motion. They possess kinetic energy. When a gas is heated, there is increase in the average kinetic energy per molecule of the gas. Hence, its temperature increases (the average kinetic energy per molecule being proportional to the absolute temperature of the gas).

[Hint : Part of Maxwell's equation, applied to a time varying magnetic flux, leads us to the equation $\oint \vec{E} \cdot \overline{ d l}=\frac{-d \phi_m}{d t}$, where $\vec{E}$ is the electric field induced when the magnetic flux changes at the rate of $\left.\frac{d \phi_m}{d t}\right]$
