1. An ideal Otto cycle with air as the working fluid has a compression ratio of 9. The minimum and maximum temperatures in the cycle are 520 and 2200 R. Accounting for the variation of specific heats with temperature, determine the following: [MO1, MO2] a. The amount of heat transferred to the air during the heat-addition process b. The thermal efficiency c. The thermal efficiency of a Carnot cycle operating between the same temperature limits
