Two gas cylinders having same capacity have been filled with 44 g of H₂ and 44 g of CO₂, respectively. If the pressure in CO₂ cylinder is 1 atm at a particular temperature, then the pressure in the hydrogen cylinder at the same temperature is

Two gases X (molecular weight M_x) and Y (molecular weight M_y ; M_y > M_x) are at the same temperature T in two different containers. Their root mean square velocities are C_x and C_y, respectively. If the average kinetic energies per molecule of two gases X and Y are E_x and E_y respectively, then which of the following relation(s) is/are true?

The ratio of root mean square velocity to average velocity of gas molecules at a particular temperature is

Gases deviate from the ideal gas behaviour because their molecules

In the ideal gas equation, the gas constant R has the dimensions of

Helium atom is two times heavier than a hydrogen molecule at 298 K, the average kinetic energy of helium is

If a gas is expanded at constant temperature

In the equation PV = nRT, which one cannot be the numerical value of R?

If P, V, M, T and R are pressure, volume, molar mass, temperature and gas constant respectively, then for an ideal gas, the density is given by
