The correct option is (A)
the first law of thermodynamics
Step-by-step explanation:
The first law of thermodynamics takes the idea of law of conservation of energy and modify it for thermodynamics systems. It is the total internal energy of the systems equals to the amount of heat added "to" the system and the workdone "by" the system given as:
ΔU = Q - W
Q = heat added TO the system
W = work BY the system
ΔU = Total internal energy
But the total internal energy is CONSERVED; it means that energy cannot be created or destroyed; it can only be transformed from one form to another. Hence the correct option is (A).
