Prоblem 1 (15 pоints) An ideаl аir-stаndard Ottо cycle (variable specific heat) has a compression ratio of 10. The expansion and compression processes are both adiabatic and reversible. At the beginning of the compression (state 1), the air in the cylinder is at 100 kPa and 300 K. The maximum gas temperature is measured to be 1060 K. (7.5 points) Determine the temperatures at the end of the compression process (state 2) and at the end of the expansion process (state 4). Remember to account for the variability of specific heat with temperature. (7.5 points) Determine the thermal efficiency of this Otto cycle. Remember to account for the variability of specific heat with temperature. Any heat or work terms you use to answer this question must come from an analysis that identifies an appropriate system, starts with general versions of any balance equations you use, and clearly identifies any assumptions you use and how they affect your analysis.
