Which of the following statement(s) is (are) correct regarding the root mean square speed (Urms) and average translational kinetic energy of a molecule in a gas at equilibrium ? (2019)
- Urms is inversely proportional to the square root of its molecular mass
- Eav is is doubled when its temprature is increased four tiomes
- Urms is doubled when its temprature is increased four times
- Eav at a given temprature does not depend on its molecular mass
Answer
(A) U rms is inversely proportional to the square root of its molecular mass, (C) U rms is doubled when its temprature is increased four times, (D) E av at a given temprature does not depend on its molecular mass
