Mr Luda wants to understand further about a newly created gas. The gas is initiallyat a pressure of 90 kPa, volume of 1.258 m3 and temperature of 10°C (State 1).The gas undergoes a 3-step process in which it is first compressed isothermally toa pressure of 400 kPa and volume of 0.283 m3 (State 2), then expanded at constantpressure back to its original volume (State 3). Finally, the gas is returned to itsoriginal State 1 by cooling at constant volume.a) Sketch the cycle of this system on a P – V diagram.b) Calculate the work done (in kJ) for each process step.c) Determine the total work done for the three-process cycle.d) State whether the work done is on or by the system.

There is a calorimeter composed of a thermally insulated container. Inside it are 1.2 kg of ice at −15 ∘C. How much mass of water at 60 ∘C needs to be added in the calorimeter for the final temperature to be 5 ∘C? If water vapor were introduced at 100 ∘C instead of water, how much mass of steam would have to be added for the final temperature to be 30 ∘C?
