Pressure is applied isothermally to a container that holds a liquid. Assuming the liquid is compressible, what has happened to the entropy? The entropy has decreased because the applied pressure results in the particles being less free to move, making their positions more predictable. The entropy has increased because the applied pressure results in heat being transferred from the environment to the system. The entropy has increased because the particles move more rapidly at higher pressure, making their velocities less predictable. None of the above.
A system is in a macrostate compatible with 5.24 x 109 possible microstates. What is the corresponding value of the entropy?
Suppose that the Earth was thermally insulated from the rest of the universe so that it was an isolated system. Describe the entropy of the Earth as a function of time.

The principle of increasing entropy Entropy principle: "For all irreversible processes, the change in entropy of the universe is positive." To prove the principle can be taken the case of reversible adibatic process. AS = Sf - Si Prove that the entropy of the universe is positive: E4S 2 0
One of the statements of the second law is that “heat cannot flow from a colder body to awarmer one without external aid”. Assume two systems, 1 and 2, at T1 and T2 (whereT2 > T1 ). Show that if a quantity of heat q did flow spontaneously from 1 to 2, the processwould result in a decrease in the entropy of the universe. [You may assume that the heat flowsso slowly that the process can be regarded as reversible. Assume also that the loss of heat bythe system 1 and the gain of heat by 2 do not affect T1 and T2 .]
(a) What is the unit of "specific entropy"? Is it an extensive property? (b) What is an isentropic process? Please give an example. (c) Explain the increase of entropy principle. (d) The entropy of a hot baked pizza decreases as it cools. Is this a violation of the increase of entropy principle? Explain.
Polymers, like rubber, are made of very long molecules, usually tangled up in a configuration that has lots of entropy. As a very crude model of a rubber band, consider a chain of N links, each of length L Imagine that each link has only two possible states, pointing either left or right. The total length L of the rubber band is the net displacement from the beginning of the first link to the end of the last link. Using the thermodynamic identity, you can now express the tension force F in terms of a partial derivative of the entropy. From this expression, compute the tension in terms of L, T , N, and l.
Suppose that 10 distinguishable particles are equipartitioned in a container that has 100 equal-sized compartments. What is the entropy on this system?
