SUMMARY
The discussion clarifies that the work done in an isothermal process is greater than in an adiabatic process when comparing the same initial and final states of pressure (P) and volume (V). The area under the curve in the P-V graph represents the work done by the gas, and it is established that for accurate comparison, an isochoric process must be introduced. This ensures that the work done in both processes can be effectively compared, confirming that isothermal expansion requires more work than adiabatic expansion.
