Question

Can you please help me with the 1st law of thermodynamics (What does the variables in the formula mean) and a example of the first law

Answer 1

The first law of thermodynamics states that energy cannot be created or destroyed, it can be changed from one form to another (transferred).

Formula:

ΔU= Q-W

Where:

ΔU= change of internal energy

Q= net heat transfer

w= net work
