Definition of state function
Function whose value depend only on initial and final state they are exact differantial
All state function follow which theroem
Eulers theorem
Heat can be completely converted in to work
No
Work can be completely converted in to heat
Yes
Inexact differential equal to exact differantial
dq+w=du
q/T=
q-w=
S
U
Define euler
Help in deceiding that a function is a state function or not
We have to find the complete differential and represent in linear fashion
When 2 variables are given
