SUMMARY
Calculating Q transferred in PV graphs involves understanding the relationship between internal energy, work, and heat transfer. The equation U = Q - W is fundamental, where U represents internal energy, Q is heat transferred, and W is work done. In isochoric processes, Q cannot be directly calculated without considering temperature changes and the specific process type, such as adiabatic conditions. Utilizing the ideal gas equation, adiabatic equations, or saturation/compressed water/refrigerant tables is essential for accurate calculations.
