Kinetic Theory ...

Final volume of the system will be nearly -

If the kinetic energy of the molecules in $$5$$ litres of helium at $$2$$ $$atm$$ is $$E$$. What is the kinetic energy of molecules in $$15$$ litres of oxygen at $$3$$ $$atm$$ in terms of $$E$$?

The average kinetic energy of the molecules of an ideal gas at $$10^{\circ}C$$ has the value E. The temperature at which the kinetic energy of the same gas becomes 2E is

$$\Delta C_p$$ for change $$N_2(g)+3H_2 (g)= 2N\! H_3(g)$$ is:

When x amount of heat is given to a gas at constant pressure, it performs $$\displaystyle \frac{x}{3}$$ amount of work. The average number of degrees of freedom per molecule of the gas is-

At ordinary temperatures, the molecules of a diatomic gas have only translational and rotational kinetic energies. At high temperatures, they may also have vibrational energy. As a result of this compared to lower temperatures, a diatomic gas at higher temperatures will have-

Which of the following expands most on the rise of an equal amount of temperature?

STATEMENT-1 : According to kinetic theory of gases the internal energy of a given sample of an ideal gas is only kinetic.
STATEMENT-2 : The ideal gas molecules exert force on each other only when they collide.

When the temperature is increased:

One mole of a diatomic gas undergoes a process $$P=\frac {P_0}{1+\left (\frac {V}{V_0}\right )^3}$$, where $$P_0, V_0$$ are constants. The  translational kinetic energy of the gas when $$V = V_0$$ is given by
