### delta U

what does it mean when it is says delta U= q+w is an adiabatic system?

In an adiabatic process, deltaH is equal to 0, so deltaU is equal to work.

An a diabetic system is the system through which no heat transfer can take place, q=0. Since delta U = q+w, delta U=w in an adiabetic system.

Within an adiabetic system, delta U would equal work because there is no heat transfer that can take place within the equation Delta U=q=w.

Adiabetic essentially means that no heat is entering or exiting, therefore it'd equate to 0 which would make deltaU equal to work.

Conceptually speaking, would an adiabatic system always be an isolated system? Or is there a more specific definition?

It would be an isolated system usually because there is no heat transfer

I believe it could also be referred to as an insulated system, as there is no heat transfer.

It wouldn’t necessarily be an isolated system because you can still do work on the system.
