## Isothermal

isochoric/isometric: $\Delta V = 0$
isothermal: $\Delta T = 0$
isobaric: $\Delta P = 0$

### Isothermal

In isothermal reactions, internal energy is always equal to 0 so -q=w?

### Re: Isothermal

That is correct. In isothermal reactions delta T = 0. Since the temperature doesn't change, the kinetic energy of the molecules of an ideal gas don't change either. Due to this delta U = 0. Because delta U = 0, 0 = q+ w, and w = -q.
