Question

Write the mathematical statement of the first law of thermodynamics explain term in its

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. ... So positive Q adds energy to the system and positive W takes energy from the system.
