The figure shows a closed cycle for a gas (the figure is not drawn to scale). The change in the
internal energy of the gas as it moves from a to c along the path abc is -200 J. As it moves from c
to d, 180 J must be transferred to it as heat. An additional transfer of 80 J to it as heat is needed as
it moves from d to a. Analyze the figure using first law of thermodynamics and determine the
work done on the gas as it moves from c to d?
