Qh
at high temperature Th
and rejects energy Qc
at lower temperature Tc
.(Qh − Qc)
for work.📝 Formula: \(n = \frac {useful work output}{input energy} =\frac {Qh - Qc}{Qh} \)
Real World Example: Think of a sponge. If you squeeze a soaked sponge, the water coming out is Qh
. The water left is Qc
. The difference is the work you did!
Step A→B:
Qh
at Th
.Real World Example: Imagine inflating a balloon. The air inside expands and pushes the balloon's walls outward!
Step B→C:
Tc
.Step C→D:
Qc
. No change in internal energy but gas is compressed.Step D→A:
Reversible Process: The system can return to its prior state with a minuscule change to its properties or surroundings.
