Question

A gas undergoes cycle: A→B (isothermal expansion), B→C (isochoric cooling), C→A (isobaric compression). Net work done by gas is positive if A→B expansion provides more work than C→A compression requires. This cycle is analogous to:
  1. A
    Carnot cycle
  2. B
    Stirling cycle variant
    Correct
  3. C
    Diesel cycle
  4. D
    Otto cycle

Correct answer

Stirling cycle variant

Explanation

Stirling cycle: isothermal expansion + isochoric process + isothermal compression + isochoric process. The described cycle is a variant.
