Question

What is the relation between the work done by external force on a body and internal energy in thermodynamics?

Answer 1

Answer:

The first law of thermodynamics is given as ΔU = Q − W, where ΔU is the change in internal energy of a system, Q is the net heat transfer (the sum of all heat transfer into and out of the system), and W is the net work done (the sum of all work done on or by the system).
