Two moles of a monoatomic perfect gas are adiabatically compressed so that the temperature rises from $2 0^{\circ}$ C to $8 0^{\circ}$ C. Find the work done on the gas in joules (one decimal).

Answer:

1496.50

Solution:

$Q = 0$ , so $W_{o n} = Δ U = n C_{v} Δ T = 2 \times 1.5 \times 8.314 \times 60 = 1496.5$ J.
