Step 1
According to the first law of thermodynamics, the change in internal energy (ΔU) of a system is equal to the heat added to the system (Q) minus the work done by the system (W). Mathematically, this is represented as: ΔU = Q - W In this case, heat is being Show more…

3000 J of heat is added to a system and 2500 J of work is done by the system. What is the change in internal energy of the system?
Ivan K.
During $200 \mathrm{~J}$ work done on the system, $140 \mathrm{~J}$ of heat is given out. Calculate the change in internal energy.
