Question

1. Explain the difference and similarities between ΔU, W, and Q?2. Explain to the reason why the first law of thermodynamics is considered as the law of energy conversion?

ΔU is the change in the internal energy of the system.

Q is the net heat transferred into the system.

W is the net work done by the system.

ΔU = Q - W

All are part of the first law of Thermodynamics.
