If 500 calorie of heat energy are added ...

If 500 calorie of heat energy are added to a system and the system does 350 calorie of work on the surroundings, what is the energy change of the system?

Text Solution

AI Generated Solution

To solve the problem, we need to determine the energy change of the system (ΔU) when heat energy is added and work is done by the system. We can use the first law of thermodynamics, which states: \[ \Delta U = Q - W \] Where: - ΔU = change in internal energy of the system ...
