Distinguish between reversible and inrreversible processes.

A Carnot engine operates between a hot reservoir at 362.0 K and a cold reservoir at 312.0 K. If it absorbs 525.0 J of heat per cycle at the hot reservoir, how much work per cycle does it deliver?   If the same engine, working in reverse, functions as a refrigerator between the same two reservoirs, how much work per cycle must be supplied to remove 985.0 J of heat from the cold reservoir?         Needs complete solution with @/100 % accuracy.

Calculate the change in entropy as 0.3989 kg of ice at 273.15 K melts. The latent heat of fusion of water is 333000 J/kg.

(a) What is the efficiency (in percent) of a cyclical heat engine in which 45.0 kJ of heat transfer occurs to the environment for every 65.0 kJ of heat transfer into the engine? % (b) How much work (in k) does it produce for 950 kJ of heat transfer into the engine? kJ Additional Materials CSScanned with CamScanner TPeadina
