Initially, 10 kg of r-134a is contained in a piston-cylinder system at 200 kpa as a saturated vapor. an 8 minute process occurs where 200 kj of heat is transferred to the refrigerant at constant pressure while a 110 volt electrical source supplies current to a resistor within the cylinder. at the end of the process, the temperature of the refrigerant is 60°c. show the process on a t-v diagram with respect to the saturation lines.
