A) the amount of work done on a system is dependent of the pathway.
B) the total work done on a system must equal the heat absorbed by the system.
C) the total work done on a system is equal in magnitude,but opposite in sign of the heat absorbed by the system.
D) the total energy change for a system is equal to the sum of the heat transferred to or from the system and the work done by or on the system.
E) in any chemical process the heat flow must equal the change in enthalpy.
