Clarification for First Law of Thermodynamics

Postby MaddyCowan3F » Tue Jan 27, 2015 8:32 pm

Would an isolated system already in the possession of energy in the form of heat, q, have a change in internal energy over a period of time? (Would the change in internal energy be equal to q, or to 0?)

no change in internal energy since no temperature or heat can be added or removed to the system since it is isolated. So the heat it has at the beginning is the same it will have at the end.
