139374 The number of air molecules per $\mathrm{cm}^{3}$ increased from $3 \times 10^{19}$ to $12 \times 10^{19}$. The ratio of collision frequency of air molecules before and after the increase in number respectively is

139375 Two gases having equal temperature $T$, equal pressure $P$ and equal volume $V$ are mixed together, If temperature of the mixture is $T$ and volume is $V$, then its pressure will be

139376 If the absolute temperature of a closed volume of gas is doubled, the mean free path of the molecules will be

139378 The mean free path $\lambda$ for a gas, with molecular diameter $d$ and number density $n$ can be expressed as

139379 When two prefect gas at absolute temperatures $T_{1}$ and $T_{2}$ are mixed, there is no loss of energy. If the masses of the molecules are $\mathrm{m}_{1}$ and $\mathrm{m}_{2}$ and the number of molecules of each gas are $n_{1}$ and $n_{2}$ respectively, then find the temperature of the mixture:
