    The Zeroth Law of Thermodynamics is essentially a law of:

    A.

    Heat conservation

    B.

    Temperature equality

    C.

    Entropy increase

    D.

    Work conversion

  2. 2.

    A.

    Pressure

    B.

    Volume

    C.

    Temperature

    D.

    Internal Energy

  3. 3.

    If System A is at 10 ∘C10 \, ^\circ C and System B is at 50 ∘F50 \, ^\circ F, are they in thermal equilibrium?

    A.

    No, because the numbers are different

    B.

    Yes, because 10 ∘C10 \, ^\circ C equals 50 ∘F50 \, ^\circ F

    C.

    No, because 1010 is less than 5050

    D.

    Yes, because all temperatures are equal in equilibrium
