Hello
The Carnot cycle has 4 stages.
1. Isothermal relaxation. The gas provides mechanical energy to the piston and receives heat.
2. Adiabatic relaxation. The gas provides mechanical energy to the piston and cools.
3. Isothermal compression. The gas receives mechanical energy from the piston and gives up heat.
4. Adiabatic compression. The gas receives mechanical energy from the piston and heats up
Carnot has shown that the efficiency of such a cycle with a gas depends only on the temperatures of hot and cold sources.
If instead of using a gas, a solid is used. This one could push the piston when it is heated. And pull it when you cool it. Are Carnot's conclusions still valid?
Carnot's book is available here. https://www3.nd.edu/~powers/ame.20231/carnot1897.pdf. On page 107, Carnot gives his point of view.
Those that we need are the expansive force acquired by solids and liquids by a given increase of temperature, and the quantity of heat absorbed or relinquished in the changes of volume of these bodies).Thank you for your reactions.
