An inventor designs a new heat engine that can be modeled on the Carnot cycle. The working gas in the heat engine is 1 mole of helium. The isothermal expansion results in the internal volume changing from 1 L to 3 L. The engine operates at Th = 150 °C and Tc = 25 °C. calculate the volume change associated with adiabatic expansion?
calculate the heat flow for each of the 4 steps?
calculate the work for each of the 4 steps?
calculate the entropy for each of the 4 steps?
calculate the q,wand entropy for the cycle?
