6b. A heat engine consisting of 0.5 mol of monoatomic gas is described by a three-path cycle with vertices A, B, and C' in the pressure-volume diagram. Point A is at 1.0 × 105 Pa pressure and 8.0 m³ volume. Point B is at 4.0 × 105 Pa pressure and 2.0 m³ volume. Path AB is isothermal, path BC is isobaric, and path CA is isochoric. Make a table of values with the following column headers: path, nature of path, change in internal energy of the gas, heat absorbed by the gas, and work done by the gas. Compute the efficiency of the heat engine. Illustrate the thermodynamic cycle in a pressure- volume diagram. Draw your axis and scale units. Label the paths.

Question
hello, I have this physics book and I want to ask how to do this problem. Hopefully you guys can reply fast because I have a test coming up soon and I cannot grasp this question.
Transcribed Image Text:6b. A heat engine consisting of o.5 mol of monoatomic gas is described by a three-path cycle with
vertices A, B, and C in the pressure-volume diagram. Point A is at 1.0 x 10° Pa pressure and 8.0 m3
volume. Point B is at 4.0 x 10 Pa pressure and 2.0 m³ volume. Path AB is isothermal, path BC is
isobaric, and path CA is isochoric. Make a table of values with the following column headers: path,
nature of path, change in internal energy of the gas, heat absorbed by the gas, and work done by the
gas. Compute the efficiency of the heat engine. Illustrate the thermodynamic cycle in a pressure-
volume diagram. Draw your axis and scale units. Label the paths.
