Question
A system releases 622 $\mathrm{kJ}$ of heat and does 105 $\mathrm{kJ}$ of work on the surroundings. What is the change in internal energy of the system?
Step 1
Mathematically, this can be represented as: \[ \Delta U = Q - W \] where: - \( \Delta U \) is the change in internal energy, - \( Q \) is the heat added to the system, and - \( W \) is the work done by the system. Show more…
