Air in an insulated piston-cylinder assembly undergoes a compression process from 100 kPa, 300 K to a second state at 600 K and 1 MPa. How much entropy is produced, in kJ/kgK? You can assume that the air is modeled as an ideal gas. Rair 0.287 kJ/kgK
In the friction-free piston-cylinder assembly, initially there is a volume of 0.1 m³ air at 300 K temperature. The air is heated at a constant pressure of 300 kPa, at a constant piston velocity and a temperature of 600 K for 30 s. In this context, calculate the power to be given to the piston as [kW]. Show the process in the diagram T (° C) - v (m³ / kg).

Air behaving like an ideal gas contained in a piston–cylinder assembly undergoes an isothermal process between end states, 1 and 2, where P1 = 10 bar, V1 = 0.1 m3, T1 = 300 K and P2 = 1 bar, V2 = 1 m3, T2 = 300 K. The work done by the process is:
Air contained in an insulated piston-cylinder assembly, initially at 8 bar, 377 °C and a volume of 0.60 m3, expands to a pressure of 2 bar.

2. A small, un-insulated closed cylinder with a freely moving piston contains air and is accidentally dropped into a lake and falls slowly to the bottom at 100 m below the surface Initially, the air in the cylinder is at atmospheric pressure of 100 kPa with a volume of 0.1 m3 and a temperature of 20°C. The lake is also at a uniform and constant temperature of 20°C. As the cylinder falls, the air...
