A gas mixture contains 8 moles of oxygen and 2 mole of argon at room temperature T. The total energy of the mixture is 

Air is filled at $$60^0$$C in a vessel of open mouth. The vessel is heated to a temperature T so that $$1/4^{th}$$ part of air escapes. The value of T is : 

$$'n'$$ moles of an ideal gas undergoes a process $$A\rightarrow B$$ as shown in the figure. The maximum temperature of the gas during the process will be :

Internal energy of $$n_{1}$$ moles of hydrogen at temperature $$150\ K$$ is equal to the internal energy of $$n_{2}$$ moles of helium at temperature $$300\ K$$. The ratio of $$n_{1}/n_{2}$$ is

The magnetic monment of a diamagnetic atom is 

If number of molecules of $${ H }_{ 2 }$$ are doubles  than that of $${ O }_{ 2 }$$, then ratio of kinetic energy of hydrogen to that of oxygen at 300 K is 

Find the approximate number of molecules contained in a vessel of volume $$7$$ litres at $$0^oC$$ at $$1.3\times 10^5$$ pascals:

Where temperature of a gas, contained in closed vessel is increased by $$5C$$, its pressure increases by $$1%$$.The original temperature of the gas was approx i - mately:- 

An ant is walking on the horizontal surface. The number of degree of freedom of ant will be
