2 kg of air contained in a piston-cylinder assembly undergoes a process from the initial state of T₁ = 400K, v₁ = 0.5 m³ to the final state of T₂ = 600K, v₂ = 0.8 m³. Assume the ideal gas model with cv = 0.72 kJ/kg . K for the air. Kinetic and potential energy effects are negligible. - Can this process occur adiabatically? Demonstrate it with formulas and calculations. If yes, determine the work, in kJ, for an adiabatic process between these states. If not, determine the direction of the heat transfer (in or out of the system). Determine the temperature of the isentropic process with the same initial state, T₁ = 400K, v₁ = 0.5 m³, and the same final specific volume: v₂ = 0.8 m³.
As shown in the figure below, a gas contained within a piston–cylinder assembly, initially at a volume of 0.1 m3, undergoes a constant-pressure expansion at p = 3 bar to a final volume of V2 = 0.16 m3, while being slowly heated through the base. The change in internal energy of the gas is 0.25 kJ. The piston and cylinder walls are fabricated from heat-resistant material, and the piston moves smoothly in the cylinder.

Thermodynamics A Piston-Cylinder system initially contains R-134a refrigerant at a temperature of 2.8 bar and 40 C, and its initial volume is 0.1 m3. First, heat is transferred to the system by keeping the piston constant and this process is continued until the pressure is 3.2 bar. the process is maintained by allowing the volume to change. At the end of this process, the temperature reaches 50C. Assuming the state changes as if balanced, calculate the following: a)He amount of heat transferred during constant pressure operation b)Show the state changes on the P-v diagram.
