If a gas is compressed isothermally then the r.m.s. velocity of its molecules
- A increases.
- B decreases.
- C remains the same.
- D first increases and then decreases.
Answer & Solution
Correct Answer
(C) remains the same.
Step-by-step Solution
Detailed explanation
The r.m.s. velocity of gas molecules is given by \(v_{rms} = \sqrt{\frac{3RT}{M}}\). For an isothermal process, the temperature (T) remains constant.
