Kinetic Theory ...

If the total number of $$H_2$$ molecules is double of the $$O_2$$ molecules then the ratio of total kinetic energies pf $$H_2$$ to that of $$O_2$$ at 300 K is :-

The relation between the ratio of specific heats $$(\gamma)$$ of gas and degree of freedom  $$'f'$$ will be :

$$3$$ mole of gas ''X"  and $$2$$ moles of gas "Y" enters from end "P" and "Q" of the cylinder respectively. The cylinder has the area of cross section , shown as
under 
The length of the cylinder is $$150cm$$. The gas "X" intermixes with gas "Y" at the point . If the molecular weight of the gases X and Y is $$20$$ and $$80$$ respectively, then what will be the distance of point A from Q?

The total Kinetic energy of $$1\ mole$$ of $${N}^{}_{2}$$ at $$27^{o}_{}{C}$$ will be approximately :-

The total kinetic energy of 1 mole of $${ N }_{ 2 }$$ at $$27^oC$$ will be approximately:

How many degrees of freedom the gas molecules have if under STP the gas density $$\rho = 1.3 kg/m^3$$ and the velocity of sound propagation in it is $$330 ms^{-1}$$?

Mean kinetic energy(or average energy) per gm molecule of a monoatomic gas is given by:

The de-Broglie wavelength of a particle accelerated with $$150\ volt$$ potential is $$10^{-10}\ m$$. If it accelerated by $$600\ volts$$ p.d. its wavelength will be

Three perfect gasses at absolute temperatures $$T_1$$, $$T_2$$ and $$T_3$$ are mixed. If number of molecules of the gasses are $$n_1$$, $$n_2$$ and $$n_3$$ respectively then temperature of mixture will be (assume no loss of energy)

The total kinetic energy of $$1$$ mole of $$N_2$$ at $$27$$C will be approximately
