In an adiobatic system, what's the relationship between heat and change in internal energy?
Q=0 in an adiobatic system because it's an insulated system (let's imagine an ideal system) where there's no temperature change. If change in internal energy is always equal to #n*Cv*dT# and there's no temperature change, then there shouldn't be a change in internal energy? But this wouldn't make sense because the system would overall just be undefined or something.
Someone please help! Thank you

Heat
The important point to realize is that an adiabatic process does not imply that there is no temperature change. An isothermal process is one in which there is no temperature change. A process is adiabatic if it occurs so quickly (or so slowly) that the energy input (into the system) by heating is zero, or in other words, no heat is lost or gained by the system.
There is a component that you are forgetting: work.
Which tells us that the work done (by system or environment depending on how you structure your signs), is equal to the change in internal energy.
We must have the the internal energy decreases in this adiabatic process. It does not remain constant.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
