Task: In a piston and cylinder assembly, the gas enclosed in the assembly is initially at 20 psia and 0.1 ft³ and it goes through a thermodynamic cycle. Process 1-2: The pressure of the gas reduces to 15 psia while the piston is fixed (volume is constant). Process 2-3: At constant pressure, the gas expands to the volume of 0.3 ft³. Process 3-4: The gas is pressurized to 30 psia while the piston is fixed. Process 4-1: The cycle is completed through a process that the pressure and volume are linearly related. Sketch the diagram of pressure as a function of volume. State 1: P₁ = 20 psia and V₁ = 0.1 ft³ State 2: P₂ = 15 psia and V₂ = 0.1 ft³ State 3: P3 = 15 psia and V3 = 0.3 ft³ State 4: P4 = 30 psia and V4 = 0.3 ft³

(Open system) Presto pan can make the cooking process faster than a regular pan because it can maintain high pressure and temperature during the cooking process. The pressure in the pan is controlled with a pressure regulator that keeps the pressure constant by releasing steam periodically to prevent pressure build-up. A presto pan with a volume of 6 L and operating at a pressure of 75 kPa. Initially the pot contained 1 kg of water. Heat goes into the pan at a rate of 500 W for 30 minutes of operation. Consider the atmospheric pressure 100 kPa, determine: а. Temperature during cooking. b. The amount of water left in the presto pan after finishing cooking
