1 kg of Diatomic gas is at a pressure of 8×104N/m2. The density of the gas is 4kg/m3 . The energy of the gas due to its thermal motion is ___

U=52μRT for Diatomic gases. (5 is the degrees of freedom)But PV=μRT V=massdensity=14m3P=8×104N/m2∴U=52×8×104×14=5×104J

Detailed Solution

$U = \frac{5}{2} μ R T$ for Diatomic gases. (5 is the degrees of freedom)
But $P V = μ R T$ $V = \frac{m a s s}{d e n s i t y} = \frac{1}{4} m^{3}$

$P = 8 \times 10^{4} N / m^{2}$

$∴ U = \frac{5}{2} \times 8 \times 10^{4} \times \frac{1}{4}$

$= 5 \times 10^{4} J$
