Problem: A system receives 425 J of heat from and delivers 425 J of work to its surroundings. What is the change in internal energy of the system (in J)?

🤓 Based on our data, we think this question is relevant for Professor Arman's class at UTSA.

FREE Expert Solution

The internal energy (ΔE or ΔU)  of the system can be calculated from the heat (q) and work (w) of the system where

 ΔE = q + w

The signs of heat (q) and work (w) of the system can be either negative or positive depending on the key words stated.
