A frictionless piston fitted inside a cylinder containing gas at a pressure of 200 kPa, volume of 1 litre and temperature of 25 °C. Carbon monoxide is to be compressed in the system and the final volume is 0.5 litre. Work is done to move the piston and heat is transferred to the cooling system around the cylinder. Illustrate the importance of expressions for work done in a thermodynamic process by applying the first principles while calculating the work done when the expansion is ADIABATIC, ISOTHERMAL and POLYTROPIC for n=1.5.

The frictionless piston and cylinder contain 1 kg of water. The initial pressure and volume are each pressure of 100kPa 0.25 m^3 (state 1). The system was gradually heated and when the volume of water in the cylinder became four times the initial volume (state 2), the piston was fixed and heating was continued until the water pressure reached 300 kPa (state 3).

A piston and cylinder device contains 0.15 kg of water at 25◦C (state 1). As shown in the figure, the piston weighs 500 N and has a cross-sectional area of 0.01 m2. Atmospheric pressure is 100 kPa. Heat is transferred to the cylinder from a reservoir at 200◦C, raising the piston. When the piston touches the stops, the volume inside the cylinder is Vmax= 0.165 m^3 (state 2).

A fluid is contained in a cylinder by a spring-loaded, frictionless piston so that the pressure in the fluid is linear function of the volume (p = a + bV). The internal energy of the fluid is given by the following equation U = 34 + 3.15 pVwhere U is in kJ, p in kPa and V in cubic metre. If the fluid changes from an initial state of 173 kPa, 0.03 m3to a final state of 400 kPa, 0.06 m3, with no work other than that done on the piston, find the direction and magnitude of the work and heat transfer.

Air is contained in a piston cylinder arrangement as shown in Fig.(Refer attachment). The piston can be assumed to be massless, frictionless, and perfectly insulated. 10 kg of dry ice (solid CO2) is placed on top of the piston. The initial conditions for air inside the cylinder are P1=121 kPa, T1= 300 K. Dry ice sublimates gradually, and its mass reduces to 5 kg. Ambient air is always at room temperature (27oC) and atmospheric pressure.
