In van der Waals equation at constant temperature 300 K, if a = 1.4 atm L mol, V = 100 mL, n = 1 mole, then what is the pressure of the gas?

Gas in a cylinder is maintained at $10 \,atm$ pressure and $300\, K$ temperature. The cylinder will explode if pressure of gas goes beyond $15\, atm$. What is the maximum temperature to which gas can be heated?

Critical temperature of CO is 304 K, it cannot be liquified above 304 K. At a certain temperature, $volume \propto\frac{1}{pressure}$

In the van der Waals equation, 'a' signifies

The value of van der Waals' constant ' $a$ ' for ammonia is larger than that of nitrogen gas. Molecular weight of ammonia is smaller than nitrogen gas.

The statement which is not correct, is

Compressibility factor for hydrogen varies with pressure with positive slope at all pressure. Even at low pressure, repulsive forces dominate for hydrogen gas.

If $P$ is pressure and $\rho$ is density of a gas, then $P$ and $\rho$ are related as

If $300\,mL$ of a gas at $27^{\circ} C$ is cooled to $7^{\circ} C$ at constant pressure, its final volume will be

Pressure in a mixture of $4 \,g$ of $O _{2}$ and $2\, g$ of $H _{2}$ confined in a bulb of 1 litre at $0^{\circ} C$ is

In the gas equation: $PV = nRT$

Which of the following gas molecules have equal total kinetic energy and translational kinetic energy?

Two different gases enclosed in different flasks $A$ and $B$ at same temperature and pressure were found to contain same number of molecules. The ratio of volumes of the flasks $A$ and $B$ must be

Which of the following gases will have the highest rate of diffusion?
