Questions in Kinetic Theory of Gases

Select	Question
	For a gas if $\gamma =1.4$, then atomicity, ${{C}_{p}}$ and ${{C}_{v}}$ of the gas are respectively
	Which of the following formulae is wrong
	In gases of diatomic molecules, the ratio of the two specific heats of gases ${{C}_{P}}/{{C}_{V}}$ is
	For hydrogen gas ${{C}_{p}}-{{C}_{v}}=a$ and for oxygen gas ${{C}_{p}}-{{C}_{v}}=b$. So the relation between a and b is given by
	For a gas the difference between the two specific heats is 4150 J/kg K. What is the specific heats at constant volume of gas if the ratio of specific heat is 1.4
	The quantity of heat required to raise one mole through one degree Kelvin for a monoatomic gas at constant volume is
	The specific heat relation for ideal gas is
	The specific heat of 1 mole of an ideal gas at constant pressure $({{C}_{P}})$ and at constant volume $({{C}_{V}})$ which is correct
	What is the ratio of specific heats of constant pressure and constant volume for $N{{H}_{3}}$
	If two moles of diatomic gas and one mole of mono atomic gas are mixed then the ratio of specific heats is
