(a) The fraction of total number of molecules of a gas having most probable velocity increases with an increase in temperature of the gas
(b) The concentration of an ideal gas at 100 K and 0.0821 atm of pressure is 0.1×10−2 mol. lit−1(R=0.0821lit.atm.mol−1.K−1)
(c) If the rms velocity of an ideal gas at T(K) is ′c′am. s−1, its rms velocity at 4T(K) is ′2C′cm.s−1
(d) The average kinetic energy of gas molecules is proportional to their absoluts temperature.
