The following four gases are at the same temperature. In which gas do the molecules have the maximum root mean square speed?

At a given temperature if $V_{rms}$ is the root mean square velocity of the molecules of a gas and $V_s$ be the velocity of sound in it, then these are related as $\left(\gamma = \frac{C_p}{C_v}\right)$

Statement 1. Boyle's law is independent of the selection of scale of temperature.$\,$ Statement 2. Boyle's law does not hold good for a gas at low temperature and high pressure.

The heat required to raise the temperature of one mole of gas by 1$^\circ$C at constant volume is $k$ times that required to raise the temperature of one mole of triatomic gas at constant pressure. What is the value of $k$ ?

The relation between volume V, pressure P and absolute temperature T of an ideal gas is $PV = x T$ where x is a constant The value of x depends upon
