ans:
- Non-pv work can't be obtained from a process for which
Explaination:
- Gibbe's energy is defined as "The amount of energy available
from the system at given set of condition that can be put in to
useful work."
- 'in simple term Gibbe's energy is one such thermodynamic
function which help in the devlopment of criterion of spontanity of
process.
- the physical significance of Gibbe's energy can be understood
from the relationship between the non-pv work and Gibbe's energy
change.
acoording to 1st law of Thermodynamics,relationship between
G and non-pV
work,
T,P =
Wnon-exp.
- so,we can say that decrease in Gibbe's energy = non-expantion
work(non-pv work)done by system.
- when is nagative
process is spontanious and non pv work is said to be done while
=0 system is
in eqilibrium state where non-pv work cant be obtained.
