5 moles of an ideal gas at 100 K are allowed
to undergo reversible compression till its
temperature becomes 200 K.
If CV = 28 JK–1mol–1, calculate $\Delta $U and $\Delta $pV for
this process. (R = 8.0 JK–1 mol–1]
$\Delta $U = 14 kJ; $\Delta $(pV) = 4 kJ
$\Delta $U = 2.8 kJ; $\Delta $(pV) = 0.8 kJ
$\Delta $U = 14 kJ; $\Delta $(pV) = 18 kJ
$\Delta $U = 14 kJ; $\Delta $(pV) = 0.8 kJ
