Why is the change of heat non zero in a isothermal process?
So $$\Delta U =0$$
And the first of law of thermodynamics becomes
$$W= -Q$$
(PS: Also, I want to point out a flaw in your question:
Even when $T$ remains same, $\Delta Q$ need not be zero. …

Adiabatic Process: Fast or Slow? [duplicate]
I have always used adiabatic process to be fast, so that the system doesn't get enough time to exchange energy in the form of heat. But as I was reviewing adiabatic process from the Resnick, Halliday, …

What is the sign convention being used in thermodynamics for calculating work done?
Given: First Law of Thermodynamics as
$$\Delta U = Q + W$$
Where,
$U$ = Total internal energy of the system.
$Q$ = Heat Supplied
$W$ = Could be work done ON or BY the system. …

What is the sign convention being used in thermodynamics for calculating work done?
I am currently studying from Daniel V. Schroeder's An Introduction to Thermal Physics. I think there is some discrepancy the way he goes from equation 1.28 to equation 1.29. I get the calculus, but I …
