Question

Derive the equation of pressure,
Volume & work​

Answer 1

Answer:

Thermodynamics. Derive an expression for pressure-volume work (PV – work). During expansion, work is done by the system and ∆V(V2 – V1) is positive. Therefore, in order to satisfy the sign conventions, a negative sign is put in the expression for work.

Answer 2

Derive an expression for pressure-volume work (PV – work). During expansion, work is done by the system and ∆V(V2 – V1) is positive. Therefore, in order to satisfy the sign conventions, a negative sign is put in the expression for work. During compression, Work is done on the system.
