    For this case what you should know is the statement of the first law of thermodynamics.

    By definition, we have to:

    • This law establishes that energy is not created, nor destroyed, but is conserved.
    • Then we have that when a certain system is subjected to a thermodynamic cycle, the heat given by the system will be equal to the work received by it, and vice versa.

    In equation mode we have to:

    Q-W = 0

    Where,

    1. Q: heat
    2. W: work done

    Answer:

    A) Energy can not be created or destroyed.
