Isothermic vs. Adiabatic
In the review session tonight, the TA used the word adiabatic to describe a reaction in which we knew q=0 because it was "adiabatic." Does adiabatic mean the same thing as isothermic?

Re: Isothermic vs. Adiabatic
I think adiabatic means something has no heat transfer while isothermic means that there is no change in temperature, but in the overall scheme of things they both refer to q=0.

Re: Isothermic vs. Adiabatic
In an adiabatic system, there is no heat transferred; therefore, the total change in internal energy of the system is equal to the work performed (deltaU=w). In an isothermal system, there's no change in temperature; therefore, the total internal energy of the system doesn't change (deltaU=0). Because of this, the heat transferred is equivalent in value to the work performed (q=-w) for isothermal.

Re: Isothermic vs. Adiabatic
They pertain to solving for change in U, as in Isothermic conditions there is no change in temp. but work is done equivalent to -q which is the change in U. For adiabatic conditions there is no heat transferred. Basically under both conditions keep in mind that q=0.
