When a gas filled in a closed vessel is heated by raising the temperature by $1^{\circ} C$, its pressure increase by $0.4 \%$. The initial temperature of the gas is ..........$K$
$70$ calories of heat are required to raise the temperature of $2$ moles of an ideal gas at constant pressure from $30°C$ to $35°C.$ The amount of heat required to raise the temperature of same gas through the same range $(30°C$ to $35°C)$ at constant volume ..... $cal$ $(R = 2 \,cal/mol/K)$
One mole of an ideal gas $\left( {\frac{{{C_P}}}{{{C_V}}}\, = \gamma } \right)$ heated by law $P=\alpha V$ where $P$ is pressure of gas, $V$ is volume, $\alpha$ is a constant what is the heat capacity of gas in the process-
The value of $\gamma\left(=\frac{\mathrm{C}_{\mathrm{p}}}{\mathrm{C}_{\mathrm{v}}}\right),$ for hydrogen, hellium and another ideal diatomic gas $X$(whose molecules are not rigid but have an additional vibrational mode), are respectively equal to
Which of the following plots represents schematically the dependence of the time period of a pendulum, if measured and plotted as a function of the amplitude of its oscillations? (Note amplitude need not be small)
At $100 \,K$ and $0.1$ atmospheric pressure, the volume of helium gas is $10 \,litres.$ If volume and pressure are doubled, its temperature will change to ....... $K$
