Question

state 1st law of thermodynamics explain its mathematical notation​

Answer 1

Answer:

The first law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the system minus the net work done by the system. In equation form, the first law of thermodynamics is ΔU = Q − W. Here ΔU is the change in internal energy U of the system.

Answer 2

first law of thermodynamics states that the change in internal energy of the system is equal to the amount of heat supplied to the system minus the amount of work done on the system by the surrounding

∆u=∆q-∆w
