Four cylinders contain an equal number of moles of argon, hydrogen, nitrogen, and carbon dioxide at the same temperature. The energy is minimum in?

The degree of freedom per molecule of a gas is $$3$$. The heat absorbed by the gas at constant pressure is $$150\,J$$. Then increase in internal energy is 

At ordinary pressure and temperature, the ratio of interatomic distance of a gas and a liquid is of the order of

One mole of distance ideal gas $$ ( \gamma = 1.4 ) $$ is taken through a cyclic process staring from point A. The process $$ A \rightarrow  B $$  is an adiabatic compression, $$ B \rightarrow  C $$ is isobaric expansion $$ C \rightarrow D $$ an  adiabatic expansion and $$ D \rightarrow  A $$ is isochoric. The volume ratios are $$ V_A /  V_B = 16 $$ and $$   V_C / V_B = 2 $$ and the temperature at A is $$  T_A = 300 K $$ Calculate the temperature of the temperature of the gas at the points B and D and final the efficiency of the cycle.

A vessel contains mixture of hydrogen and oxygen gases in teh ratio of their masses equal to 1:5. The ratio of mean kinetic energy of the two gases is

The mean kinetic enrgy of one gm-mole of a perfect gas at absoulte temperature T is 

An ideal gas has volume $$V$$ and pressure $$P$$. The total translational kinetic energy of all the molecule of the gas is.

When an ideal diatomic  gas is heated  at constant pressure.  the  fraction of   the heat energy supplied  which increases  the internal energy of he gas is 

Calculate the total KE of the mixture of 4 gm  $$H_{2}$$  and 4 gm He at 300 K-`

For silver , $$C_p(JK^{-1}mol^{-1})=23+0.01T$$. If the temperature (T) of 3 moles of silver is raised from $$300K$$ to $$1000K$$ at $$1\ atm$$ pressure, the value of $$\Delta H$$ will be close to:
