1. The fraction of total number of molecules of a gas having most probable velocity increases with an increase in temperature of the gas
2. The concentration of an ideal gas at 100 K and 0.0821 atm. of pressure is 1.0 x 10-2 mol. Lit-1 (R = 0.0821 lit. atm. Mol-1K-1)
3. If the rms velocity of an ideal gas at T(K) is 'C’ cm. s-1, its rms velocity at 4T(K) is '2C’ cm.s-1
4. The average kinetic energy of gas molecules is proportional to their absolute temperature
The fraction of total number of molecules of a gas having most probable velocity increases with an increase in temperature of the gas
