Choose the incorrect statement from the following.

At Boyle temperature a real gas obeys ideal gas law over an appreciable range of pressure.

Critical temperature of $\mathrm{CO}_2$ is $27.5^{\circ} \mathrm{C}$.

Above critical temperature, a real gas behaves like an ideal gas.

At room temperature and 1 atm pressure the compressibility factor $(Z)$ for $\mathrm{H}_2$ gas is greater than 1 .
