Could you explain a little more, I don't understand ?If the gas cooled and compressed itself to where it started, the conservation of energy balance wouldn't work out.
A thermodynamic cycle is a series of processes that a system undergoes and eventually returns to its original state. It is also known as a closed system because no mass enters or exits the system during the cycle.
Liquid and gas are two different states of matter that can be present in a thermodynamic cycle. A liquid has a fixed volume and takes the shape of its container, while a gas fills the entire container and has no fixed shape or volume.
In a thermodynamic cycle, heat transfer occurs through two main mechanisms: conduction and convection. In conduction, heat is transferred through direct contact between the liquid or gas and a heat source. In convection, heat is transferred through the movement of the liquid or gas particles.
Some common examples of thermodynamic cycles with liquid and gas include the Carnot cycle, the Rankine cycle, and the Brayton cycle. These cycles are commonly used in power plants to convert heat energy into mechanical work.
The second law of thermodynamics states that in any energy conversion process, the total entropy of a closed system always increases. In a thermodynamic cycle with liquid and gas, this means that some energy is always lost as heat due to inefficiencies in the system, leading to an overall increase in entropy.
