One mole of an ideal monoatomic gas at $T_{0} = 300$ K expands slowly according to $P = kV$ until its temperature is $3 T_{0}$ . Find the heat supplied in joules (nearest integer).

Answer:

9977

Solution:

$k V^{2} = RT$ . $Δ U = \frac{3}{2} R (2 T_{0}) = 3 R T_{0}$ . $W = \frac{k}{2} (V_{2}^{2} - V_{1}^{2}) = \frac{R}{2} (2 T_{0}) = R T_{0}$ . $Q = 4 R T_{0} = 4 \times 8.314 \times 300 = 9977$ J.
