A perfect gas of volume 10 litre n compressed isothermally to a volume of 1 litre. The rms speed of the molecules will (a) decrease 5 times (b) remain unchanged (c) increase 5 times (d) increase 10 times

Answer: (b). vrms = √(3RT/M) depends only on T. Isothermal: T is constant, so vrms does not change. So the answer is (b) remain unchanged.
