One kg of a diatomic gas is at a pressure of \(8 \times {10^4} N/{m^2}\). The density of the gas is \(4 kg\,\,/\,\,{m^3}\). What is the energy of the gas due to its thermal motion
1 \(3 \times {10^4}\,\,J\)
2 \(5 \times {10^4}\,\,J\)
3 \(6 \times {10^4}\,\,J\)
4 \(7 \times {10^4}\,\,J\)
Explanation:
\(K \cdot E=\dfrac{5}{2} n R T=\dfrac{5}{2} P V\) \(K.E = \frac{5}{2}P\left( {\frac{m}{\rho }} \right) = \frac{5}{2} \times 8 \times {10^4} \times \frac{1}{4} = 5 \times {10^4} J\)

A gas in a vessel is at the pressure \(P_{0}\). If the masses of all the molecules be made half and their speed be made double, then the resultant pressure will be
1 \(2 P_{0}\)
2 \(4 P_{0}\)
3 \(P_{0} / 2\)
4 \(P_{0}\)
Explanation:
Let \(P_{0}=\dfrac{1}{3} \dfrac{m n}{V} c^{2}\) \(P^{\prime}=\dfrac{1}{3} \dfrac{\left(\dfrac{m}{2}\right) n}{V}(2 c)^{2}=2 P_{0}\)
