What are the things must be remember while studying adiabatic processes?
1 Answer
Well, it's always important to remember the definition of an adiabatic process:
#q = 0# ,
So, there is no heat flow in or out (the system is thermally insulated from the surroundings).
From the first law of thermodynamics:
#DeltaE = q + w = q - intPdV# where
#w# is the work from the perspective of the system and#DeltaE# is the change in internal energy.
For an adiabatic process, we then have
From the second law of thermodynamics:
#DeltaS >= q/T# where
#># corresponds to irreversible processes and#=# corresponds to reversible processes.
If there is absolutely no heat flow in or out, the system entropy should be constant, as long as the process is reversible. [You can read more about reversible processes here.](https://socratic.org/questions/why-does-the-entropy-is-defined-by-q-reversible-what-is-the-meaning-of-defining-)
