What is the difference between an exact and and inexact differential?
These were introduced in my physics 2 book with the first law of thermodynamics represented by differentials,
dEint= dQ + dW
Then, it has a note that says
"Note that dQ and dW are not true differential quantities because Q and W are not state variables; however dEint is. Because dQ and dW are inexact differentials, they are often represented by the symbols dQ and dW ,both with lines through the vertical part of the d's. Sorry, I it wouldn't let me open the latex instructions.
Thanks- Erik
