Thermodynamics Process:
- When a system changes its state from one equilibrium state to another state, then the path of successive states through which the system has passed is known as thermodynamic process.
- The process of heating and cooling of a gas is defined as thermodynamic process.
It is observed that during the thermodynamic process, changes takes place in various properties of the gas such as pressure, volume, temperature, specific energy, specific enthalpy etc.
Types of Thermodynamics Process:
There are several specific types of thermodynamic processes that happens
frequently enough in practical situations that they are commonly deals in the study of thermodynamics. Each has a unique characteristics that
identifies it, and which is useful in analyzing the energy and work
changes related to the process.
- Isochoric process - a process with no change in volume, in that case the system does no work.
- Isobaric process - a process with no change in pressure.
- Isothermal process - a process with no change in temperature.
- Adiabatic process - a process with no heat transfer into or out of the system.
It
is possible to have multiple processes within a single process. The
most clear example would be a case where volume and pressure change,
resulting in no change in temperature or heat transfer - such a process
would be both adiabatic & isothermal process.
Thermodynamics Cycle or Cyclic Process:
When a process or processes are performed on a system in such a way that the final state is identical with the initial state, it is then known as thermodynamic cycle or cyclic process.
