PROCESS B ->C
THE ISOBARIC PERFORMANCE STROKE
Process B->C is the PERFORMANCE STROKE of this engine because this is when the machine lifted the load. Lifting the load was the purpose of the engine. The process is isobaric because it happens at atmospheric pressure, while the load keeps a constant push (resistance) on the piston. Report the measured pressures here:
The Formula for Internal Energy Change. Use this space to derive a general formula that will allow you to calculate the change in internal energy experienced by the gas (the air) during isobaric process B->C, in terms of only the known quantities P,V, and T, without using (or determining) n. Assume air is a diatomic ideal gas.
