Task 4
The system contains carbon dioxide at 300 kPa, with volume of 0.2 m³ and is at 100°C. The mass
has been added at such that the gas compresses to a final temperature of 200°C, and the work
done by the system is 80.4 kJ. Analyze, describe the operation of the system and their properties
and calculate the index of compression in the polytropic process.
Task 5
A sample of gas is compressed by an average pressure of 2 atm which decrease its volume from
400 cm 3 to 200 cm . During the process, 10 J of heat is rejected to the surroundings. Explain
and demonstrate the application of the first law of thermodynamics to this system and calculate
the change in energy of the system.
