Kinetic Theory ...

Critical temperature of a gas obeying van der waals' equation is : 

An ideas monotonic gas is taken through cyclic process ABCA as given in figure, what will be the ratio of heat absorbed and released by gas during process?

$$70$$ calories of heat is required to raise the temperature of $$2$$ moles of an ideal gas at constant pressure from $$ 30^0 C$$ to $$35^0 C $$ ( R = 2 cal/mol-^0C ). The amount of heat required to raise the temperature of the same gas through the same range at constant volume is 

The speed of sound in oxygen $$ (O_2) $$ at a certain temperature is $$ 460 ms^{-1} $$.The speed of sound in helium (He) at the same temperature will be (Assume both gasses to be ideal) 

A diatomic ideal gas is heated at constant volume unitl its pressure is doubled- the molar heat capacity for the whole process is 

The molar heat capacity of water at constant pressure $$P$$ is $$75J{K}^{-1}$$ $${mol}^{-1}$$. When $$1.0kJ$$ of heat is supplied to $$100g$$ of water which is free to expand, the increase in temperature of water is:

A filled gas characterized by parameter P,V and T and another jar B filled with a gas with parameter 2P, V/4 and 2T. The ration of the number of molecules in jar A to those in jar B in-

One mole of $$O_2$$ gas is contained in a box of volume $$V = 2m^3$$ at pressure $$P_0$$ and temperature $$300 \,K$$. The gas is now heated to $$600 \,K$$ and the molecules now get dissociated into oxygen atoms. The new pressure of the gas is

A diatomic gas of molecules weight $$40gm/mole$$ is filled in a container at $$300K$$. It is moving at a velocity $$200m/s$$. If it is suddenly stopped, the rise in temperature of gas is:

The average kinetic energy per molecule of an ideal nonliner polyatomic gas at the room temperature $$ T_0 $$ will be (k is boltzman constant, neglect vibrational modes)
