Consider a gas with density $\rho $ and $\bar c$ as the root mean square velocity of its molecules contained in a volume. If the system moves as whole with velocity $v,$ then the pressure exerted by the gas is
According to law of equipartition of energy the molar specific heat of a diatomic gas at constant volume where the molecule has one additional vibrational mode is :-
A pressure cooker contains air at $1$ atm and $30^o C$. If the safety value of the cooler blows when the inside pressure $ \ge 3$ atm, then the maximum temperature of the air, inside the cooker can be .... $^oC$
A hydrogen cylinder is designed to withstand an internal pressure of $100 \,atm$. At $27^{\circ} C$, hydrogen is pumped into the cylinder which exerts a pressure of $20 \,atm$. At what temperature does the danger of explosion first sets in ......... $K$
The given diagram shows isotherms for a fixed mass of an ideal gas at temperature $T_1$ and $T_2$ . What is the value of the ratio $\frac{{{\text{r}}{\text{.m}}{\text{.s}}{\text{. speed of the molecules at temperature }}{{\text{T}}_{2{\text{ }}}}}}{{{\text{r}}{\text{.m}}{\text{.s}}{\text{. speed of the molecules at temperature }}{{\text{T}}_1}}}$ ?
The temperature of a gas is $ -68^\circ C$. At ...... $^oC$ temperature will the average kinetic energy of its molecules be twice that of at $ -68^\circ C$
