A gas expands in a frictionless piston-cylinder arrangement. The expansion process is very slow, and is resisted by an ambient pressure of 100 kPa. During the expansion process, the pressure of the system (gas) remains constant at 300 kPa. The change in volume of the gas is 0.01 m3. The maximum amount of work that could be utilized from the above process is.

1 kg of ice from a freezer at -10◦C is placed in a bucket in the garden where the temperature is 20◦C. The temperature difference between the garden and the ice/water system is used to operate an engine. Calculate the maximum amount of work that can be done by this engine and its overall efficiency.
Calculate the work (in kJ) when substance initially at 218 kPa, 9 m³ is expanded to 61 kPa in a process where PV = Const.
A piston-cylinder device initially contains CO2 at 200 kPa and 400°C and the total enclosed volume is 300 litres. Due to heat loss, the piston moves downwards to a position where it sits on a pair of stoppers and its final enclosed volume is 150 litres. Further heat loss leads to the pressure being reduced to 160kPa. Workout 1) the final temperature, 2) the total work done by CO2 and 3) the total heat transferred to CO2. Also make some comments on the result of heat and create a schematic p-v diagram of the process. The following assumptions are to be made: CO2 is a perfect gas and its molecular mass is 44kg/kmol. The ratio of specific heat capacities, γ (gamma) is 1.3 The volume occupied by the stoppers is to be ignored. There is no leakage in the system There is no friction between the cylinder and piston walls and the piston moved slowly at the same speed therefore, no acceleration. For the conversion from Celsius to Kelvin, use 273 Use 8314.5 J/kmol.K for the universal gas…
