Consider the T-V diagram of a thermodynamic process. Using the details shown in the figure, find out the molar heat capacity of the gas at the point Q. Consider the gas to be ideal and monoatomic.

Options:

Answer:

Solution:

$C d T = P d V + 1.5 R d T$ , so $C = \frac{P}{d T / d V} + 1.5 R$ . The tangent at Q passes through the origin: $\frac{d T}{d V} = \frac{T}{V}$ , giving $C = \frac{P V}{T} + 1.5 R = R + 1.5 R = 2.5 R$ . [0pt]
