what are various type of thermodynamic processes ? AND what is the first law of thermodynamics ?
Thermodynamic Processes: A thermodynamic process occurs when the system changes from initial state to a final state. The thermodynalic processes are as follows.:
1.Isothermal process: when a change in system, i.e , when a process is carried out in such condition when the temperature remains constant throughout, the process is called as isothermal process.
2.Adiabatic Process: When a process is carried in such a condition where neither heat can flow from the system nor it can enter to the system and the total heat content is constant, then the process is called as Adiabatic Process.
3.Isoochoric Process: In, this process, the volume of the system is kept constant and so it is called Isochoric process.
4.Isobaric process: In this process the pressure of the system is kept constant and so it is known as the Isobaric Process.
First Law of Thermodynamics: The First law of Thermodynamics is nothing but simply a law of conservation of energy, which states that
"Energy can neither be created nor be destroyed although it may be converted from one form to another."
Or in other words, the total energy of the universe is constant, but it may undergo transformation from one form to another. It means, the energy of an isolated system is constant.
