The ratio of two specific heats $\frac{C_P}{C_V}$ of $CO$ is

If a gas has $n$ degrees of freedom, then the ratio of $\frac{C_p}{C_V}$ is

$310 \ J$ of heat is required to raise the temperature of $2 \ moles$ of an ideal gas at constant pressure from $25 \ ^oC$ to $35 \ ^oC$. The amount of heat required to raise the temperature of the gas through the same range at constant volume is $.... \ J$.

If $\Delta Q$ is the amount of heat supplied to $n$ moles of a diatomic gas at constant pressure,$\Delta U$ is the change in internal energy,and $\Delta W$ is the work done,then the ratio $\Delta W : \Delta U : \Delta Q$ is

Which of the following formulae is wrong?

The specific heat of a gas at constant volume is $21.2 \, J/mol/^{\circ}C$. If the temperature is increased by $1^{\circ}C$ keeping the volume constant,the change in its internal energy will be ...... $J$.
