Question

write about the Nature of work (W)​

Answer 1

Answer:

Nature of work (W) : In mechanics the work is defined as the energy by which body is displaced through a distance d with an application of force. Thus,

W = f × d

In thermodynamics the type of work involved is pressure-volume or PV work, that is, work is done when the system (gas) expands or contracts against the external opposing force
