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