Two moles of oxygen at 300 K are adiabatically compressed until the pressure rises eightfold. Find the work done on the gas in kJ (one decimal, $R = 8.314$ J $m o l^{- 1}$ $K^{- 1}$ ).

Answer:

10.10

Solution:

$T_{2} = 300 \times 8^{0.2857} = 543.4$ K. $W_{o n} = n C_{v} Δ T = 2 \times 2.5 \times 8.314 \times 243.4 = 10.1$ kJ.
