(A) Explain with examples by making three separate definitions of the second law of thermodynamics.(B) What is "heat death" in the universe? How do you see the future in light of the changes in the universe from the big bang to the present?
Entropy is often called “time’s arrow” because it tells usin which direction natural processes occur. If a moviewere run backward, name some processes that you mightsee that would tell you that time was “running backward
The temperature in the deep interiors of some giant molecular clouds in the Milky Way galaxy is 50 K. Compare the amount of energy that would have to be transferred to this environment to the amount that would have to be transferred to a room temperature environment to bring about a 7.7 J/K increase in the entropy of the universe in each case.
