b. the work done by a thermodynamic system depends only on the initial and final states of the system.
c. the amount of heat added or removed from a thermodynamic system depends only on the initial and final states of the system. d. the amount of heat added or removed from a thermodynamic system depends on the path taken on a pv diagram. e. the first law of thermodynamics extends the principle of conservation of momentum to include molecular collisions.
the work done by a thermodynamic system is equal to the area under the curve on a pv diagram.
