The system absorbs 25 kJ of heat, calculate the work of the system if there is no change in internal energy?
Question
Solution 1
According to the first law of thermodynamics, the change in internal energy of a system is equal to the heat added to the system minus the work done by the system. Mathematically, this is represented as:
ΔU = Q - W
Where: ΔU is the change in internal energy, Q is the heat added to the system, and
