## Types of Systems

$w=-P\Delta V$
and
$w=-\int_{V_{1}}^{V_{2}}PdV=-nRTln\frac{V_{2}}{V_{1}}$

### Types of Systems

Are reversible processes always a certain type of system (closed, isolated, open)? What about irreversible processes? Like for reversible processes is it always going to be the same type of system or can it be different?

I think for both irreversible and reversible systems are closed systems since they both just deal with the transfer of energy

What is the conceptual difference between an irreversible expansion and a reversible expansion?

During the process of reversible expansion, the pressure from both sides of the system, external and internal, are equal. However, an irreversible expansion demonstrates a difference in external and internal pressures.
