Physics · Thermodynamics
One mole of an ideal gas in an initial state A undergoes a cyclic process ABCA, where AB is an isothermal expansion process from volume V0 to 8V0, BC is an isobaric compression, and CA is an isochoric process. The pressure at A is P0. Choose the correct statement(s) from the following options:
- 1Both A and C✓
- 2Work done by the gas in process AB is P0V0 ln 8
- 3Pressure at C is P0/4
- 4Internal energies at A and B are the same
Correct answer
Both A and C
