Thermodynamics processes (part 1) Just as a system and its surroundings were defined, processes that Systems Can be subjected to must be defined An operation by which a System Changes from one state to another is called a process. These can be I sothermal, adiabatic, is a baric, Iso Cholic, reversible or illeversible and cyclical processes. • Iso thermal: When The Temperature of the system remains Constant during various operations, Thermodynamics processes (part 2) the process is called Isothermal process. For example the expansion of a gas ever So slowly using a thermostat Small changes in Temperature in the system are immediately Counteracted by the thermostat • Adiabatic: No exchange of Heat Occurs between the system and the Surroundings, Thus in such processes there is always Change in the Temperature Such a process is called Adiabatic Process This is exemplified by Confining a gas in a Container insulated thermally from the Surroundings. When the gas expands, its Temperature falls and vice versa • Isobaric. when the pressure on a system remains constant during any Change, for example the Conversion of 1 mole of water at 2si and 1 atm to 1 mole of steam af 1000 and 1 atm.
