## Delta U

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

### Delta U

What is the equation that relates delta U, work, and time?

### Re: Delta U

Delta U is the change in internal energy of a system. The change in internal energy (dU) is equal to q+w, where q is the heat lost or gained and w is the work done on or by the system. (du=q+w) In the instance that the process occurs under constant pressure, du=dH+w, because qp=dH. If the process occurs isothermally, then dU=0 and q=-w. I am not sure what you mean by an equation that relates dU, time, and work; sorry I cannot help in that area. I hope this brief explanation helps though!

### Re: Delta U

Not sure if we learned it since thermodynamics/thermochemistry doesn't relate to time at all. Maybe you mean temperature? or something like that?
