Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.

Krypton in a closed system is compressed adiabatically from 74 K and 1 bar to a final pressure of 24 bar. What is the final temperature in K? Assume krypton is an ideal gas. From Appendix B in the text, we can assume the heat capacity of krypton is independent of temperature and CP=2.5R , where R is the molar gas constant R=8.314 J/(mol K). For an ideal gas, recall CV=CP−R=1.5R. Report your answer in units of K using three decimal places.
A gas with specific volume v₁ = 1 m³/Kg and pressure p₁=1bar in a closed system undergoes a thermodynamic cycle which consists of the following three separate processes: 1->2: Isobaric compression to v₂-0.25 m³/Kg 2->3: Isometric heating. 3->1: Isothermal expansion (pV = constant) to the initial volume. Calculate the specific work produced by the gas per cycle. Present your answer in kJ/kg.

Select one: 8 kJ of heat are absorbed b. 4 kJ of heat are rejected 12 kJ of heat are rejected O d. 10 kJ of heat are absorbed
A gas is contained in a vertical piston-cylinder assembly by a piston with a face area of 60 in2 and weight of 100 lbf. The atmosphere exerts a pressure of 14.7 lbf/in² on top of the piston. A paddle wheel transfers 3 Btu of energy to the gas during a process in which the elevation of the piston increases slowly by 2 ft. The piston and cylinder are poor thermal conductors, and friction between the piston and cylinder can be neglected. Determine the work done by the gas on the piston, in Btu, and the change in internal energy of the gas, in Btu. Step 1 Determine the expansion work done by the gas on the piston, in Btu. Wexp = i Btu
