Kinetic Theory ...

The ratio of adiabatic to isothermal elasticity of  diatomic gas is:-

A vessel contains 28 gm of $$N-2$$ and 32 gm of $$O_2$$ at temperature T = 1800 K and pressure 2 atm pressure it $$N_2$$ dissociates $$30%$$ and $$O_2$$ dissociates $$50%$$ if temperature remains constant. 

An ideal gas has an initial volume $$V$$ and pressure $$P$$. In doubling its volume the minimum work done will be in (of the given processes):

The velocities of sound in an ideal gas at temperature $$T_1$$ and $$T_2 k$$ are found to be $$V_1$$ and $$V_2$$ respectively.If the r.m.s. velocities of the molecules of the same gas at the same temperatures $$T_1$$ and $$T_2$$ are $$v_1$$ and $$v_2$$ respectively then

A gas undergoes a process such that $$P \propto \dfrac{1}{T}$$. If the molar heat capacity for this process is $$24.93 \,J/mol \,K$$, then what is the degree of freedom of the molecules of the gas?

A vessel contains a non-linear triatomic gas. If $$50$$% of gas dissociate into individual atom, then find new value of degree of freedom by ignoring the vibrational mode and any further dissociation 

At which of the following temperature would the molecules of a gas have twice the average kinetic energy they have at $${20}^{o}C$$

The lowest pressure(the best Vaccum) that can be created in laboratory at 27 degree is $$10^{-11} $$ mm of Hg. At this pressure, the number of ideal gass molecules per $$cm^{3}$$ will be

Which graph shows how the average kinetic energy of the particles varies with absolute temperature for an ideal gas?
