Question
Pick the correct statement (s) :
Options
A.The rms translational speed for all ideal-gas molecules at the same temperature is not the same but it depends on the mass.
B.Each particle in a gas has average translational kinetic energy and the equation 1/2 mv2rms = 3/2 kT establishes the relationship between the average translational kinetic energy per particle and temperature of an ideal gas. It can be concluded that single particle has a temperature.
C.Temperature of an ideal gas is doubled from 100oC to 200oC. The average kinetic energy of each particle is also doubled.
D.It is possible for both the pressure and volume of a monoatomic ideal gas to change simultaneously without causing the internal energy of the gas to change.
Solution
Vr.m.s. = 
Since PV = nRT therefore P and V both can change simultaneously keeping temperature constant.
Since PV = nRT therefore P and V both can change simultaneously keeping temperature constant.
