SUMMARY
The discussion centers on the calculation of heat transfer (ΔQ) and internal energy change (ΔU) in thermodynamic processes involving ideal gases. The specific heat capacity used in the calculations is Cv, as internal energy for an ideal gas is solely a function of temperature. The work done by the gas (ΔW) can be determined using the trapezium area under the pressure-volume curve. The overall change in internal energy for a complete cycle is zero, as the system returns to its initial state.
