Increase in tempertaure of a gas filled in a container would lead to: (a) increase in its kinetic energy (b) decrease in intermolecular distance (c) decrease in its pressure (d) increase in its mass

Answer: (a). Average KE of molecules = 3/2kT, so it rises with temperature. In a closed container volume and mass stay fixed, and pressure rises with T, so (b), (c), (d) are wrong. So the answer is (a).

Increase in tempertaure of a gas filled in a container would lead to:

Show answer and solution

Answer: (a)

Average KE of molecules $= \frac{3}{2}kT$ , so it rises with temperature.
In a closed container volume and mass stay fixed, and pressure rises with $T$ , so (b), (c), (d) are wrong.
So the answer is (a).
