Sadi Carnot

Contributions in the toolbox

1. 1824

   Establishes the maximum efficiency bound any heat cycle can approach.

   → Rankine Cycle Efficiency (Ideal)
2. 1824

   Publishes the reversible-cycle argument that efficiency depends only on reservoir temperatures.

   → Carnot Efficiency Limit
3. 1824

   Establishes the temperature-only limit on cycle efficiency — the Carnot COP.

   → Refrigeration Cycle COP
4. 1824

   Establishes the reversible-cycle temperature limit on heat-to-work conversion.

   → Heat-Pump COP + Reversible Limit
5. 1824

   Analyzes the reversible heat-engine cycle underpinning entropy.

   → Entropy Change (Ideal Gas)
