  • There are four laws governing thermodynamics.
Question 1:
There are four laws governing thermodynamics. The zeroth is concerned with thermal equilibrium of three systems, the first law describes that the total energy of the universe remains constant and the second law tells us that entropy of a non-equilibrium system will increase over time. What does the third law of thermodynamics describe?
A. As temperature approaches absolute zero, the entropy of a system approaches a constant (Avogadros number).
B. As temperature approaches absolute zero, the entropy of a system approaches critical mass.
C. As temperature approaches absolute zero, the entropy of a system approaches a constant (zero).
D. As temperature approaches absolute zero, the entropy of a system approaches infinity.
