Kinetic Theory ...

70 calorie of heat required to rise the temperature of 2 mole of an ideal gas at constant pressure from $${30^o}$$C to $${35^o}$$C. The degrees of freedom of the gas molecule are,,

If the total energy of a $$H_2$$ gas molecule is x, the linear energy of the gas molecule is 

Three perfect gases at absolute temperatures $$T_1, T_2$$ and $$T_3$$ are mixed. The masses of their molecules are $$m_1, m_2$$ and $$m_3$$ and the number of molecules are $$n_1, n_2$$ and $$n_3$$ respectively. Assuming no loss of energy, the final tempreture of the mixture is 

A mass of liquid with volume V, completely turns into a gas of volume $$V_2$$ at a constant external pressure P and temperature T. The latent heat of vapourisation is L for the given mass. Then change in the internal energy of the system is

A jar contains a mixture of oxygen and helium gases in the ratio 64 : 1. Ratio  of their mean translational energies at same temperature is

Correct statement

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.

one mole of mono atomic ideal gas follows a process AB, as shown. The specific heat of the process is $$\dfrac{13R}{6}$$. Find the value of X on P-axis.

A particle located at $$x=0$$ at time $$t=0$$, starts moving along the positive x-direction with a velocity $$v$$ tha varies as $$v=\alpha \sqrt{x}$$, the displacement of the particle varies with time as

An electric bulb of volume $$250\ cm^{3}$$ has been sealed at a pressure of $$10^{-3} mm$$ of mercury and temperature $$27^{\circ}C$$. Find the number of air molecules in the bulb. What is the average distance between the molecules?
