Question

Briefly explain the thermodynamic processes.

Answer 1

Let us first get some idea about the thermodynamic processes. Thermodynamic processes are divided into three categories in classical thermodynamics: $\left( 1 \right)$changes in a system, $\left( 2 \right)$cycles in a system, and $\left( 3 \right)$flow processes.

Complete step-by-step solution:
A transition from an initial to a final state of thermodynamic equilibrium defines a change in a system. The actual course of the process is not the fundamental issue in classical thermodynamics, and it is frequently overlooked. Unless it is disrupted by a thermodynamic operation that commences a thermodynamic process, a condition of thermodynamic equilibrium remains constant.
A cyclic process moves a system through a series of stages, beginning and ending in a specific condition. The descriptions of the system's staged states aren't the most important thing. The sums of matter and energy inputs and outputs to the cycle are of vital relevance. While the concept of the thermodynamic state variable was being created, cyclic processes were key conceptual devices in the early days of thermodynamic inquiry.
A flow process is a constant state of flow into and out of a vessel with certain wall properties, as defined by flows through the system. The state of the vessel's contents on the inside isn't the main concern. The primary quantities of concern are the states of the inflow and outflow materials, as well as the heat, work, and kinetic and potential energies transferred for the vessel. Engineering is fascinated by flow processes.

Note:
In nature, only natural processes take place. A natural process in thermodynamics is an irreversible transfer between systems that raises the sum of their entropies. Natural processes can occur spontaneously when a restriction is removed or when another thermodynamic action is performed, or they can be triggered in a metastable or unstable system, such as when a supersaturated vapour condenses. Friction is a fundamental property of natural thermodynamic processes that involve the transfer of matter or energy between a system and its surroundings, according to Planck.
