19)As both.are at same temperature then both the gases have the same kinetic energy
(D) is correct.
Because average kinetic energy depends only on temperature.
20) effusion is the passes of gas and diffusion is the mixing of gas molecules.
(C) is correct.
21)(c) is correct option. As H2 has lower molar mass so it has higher speed
