SUMMARY
Thermodynamic processes can indeed occur at changing pressure while maintaining constant temperature, as evidenced by the behavior of substances in the saturated liquid/vapor region on Pressure-Volume (Pv) and Pressure-Temperature (Pt) diagrams. When a substance transitions from the saturated region to the critical point under these conditions, it remains in the critical region on both diagrams despite the temperature being constant. This phenomenon is largely influenced by the presence of moisture in the vapor, which can change as the mixture heats up, leading to a conversion of moisture to gas and altering the state of the mixture.
