A mixture of one mole of monoatomic gas and one mole of a diatomic gas (rigid) are kept at room temperature $\left(27^{\circ} \mathrm{C}\right)$. The ratio of specific heat of gases at constant volume respectively is:
Consider a mixture of $n$ moles of helium gas and $2 n$ moles of oxygen gas (molecules taken to be rigid) as an ideal gas. Its $\frac{\mathrm{C}_{\mathrm{P}}}{\mathrm{C}_{\mathrm{V}}}$ value will be
The specific heat of a gas at constant volume is $21.2\, J/mole/°C.$ If the temperature is increased by $1°C$ keeping the volume constant, the change in its internal energy will be ...... $J$
Consider a $1\, c.c.$ sample of air at absolute temperature ${T_0}$ at sea level and another $1 cc$ sample of air at a height where the pressure is one-third atmosphere. The absolute temperature $T$ of the sample at that height is
$Assertion :$ The root mean square and most probable speeds of the molecules in a gas are the same.
$Reason :$ The Maxwell distribution for the speed of molecules in a gas in symmetrical.
