Exactly one mole of an ideal gas with a cv, m of 3.5 r serves as the working substance during a carnot cycle. the high temperature is 800.0 k and the low temperature is 373.15 k. during the isothermal expansion, the work done by the gas is 4.184 × 10 calculate (a) the thermodynamic efficiency (as a percentage) of the carnot cycle. (b) the amount of heat that is absorbed from the hot source i. e. qh) (c) the amount of heat that is released to the cold sink (i. e. qc) (d) the amount of work done by the gas in each cycle.
