Question

Explain the reversible and Irreversible processes. Describe the working of Carnot engine. Obtain an expression for the efficiency.

Answer 1

According to the Carnot theorem, thereversible engine will always have a greater efficiency than theirreversible one. The reversible heatengine operates on a reverse cycleand functions as a heat pump (or refrigerator). The Carnot cycle isreversible representing the upper limit on the efficiency of an engine cycle.

Answer 2

reversible are the process in which an object can come to its original form and then Irreversible is a process in which the object does not come in its original form for example reversible object is equal to ice cube and Irreversible object is equal to burning of paper
