Step 1. Understanding the Slopes in the log P vs. log V Diagram:
Process A has a slope of , where , indicating an adiabatic process (since ). Process B has a slope of or , suggesting that it is an isothermal process (since ).
Step 2. Using Heat Capacities for Adiabatic and Isothermal Processes:
For an adiabatic process (), the heat capacity is effectively zero because no heat exchange occurs ( for adiabatic). For an isothermal process (), the heat capacity tends to infinity because any heat added is used to perform work without changing temperature.
Conclusion:
Therefore, the correct statement is:
