A-Sf>Si
*Sf<Si
*Si=Sf
B-Yes,since entropy is d measure of disorderness.since here the system approach towards equilibrium so entropy decrease and become constant at equilibrium hence disorder decrease I.e system get orderde

2. Imagine that we have two large copper blocks, A and B, which are isolated from the surroundings. Block A is at a temperature of 250 K, and block B is at a temperature of 300 K. As the blocks are large, we can assume that a small amount of heat flowing into or out of them is reversible, and that such a process will not change the temperature of the block. It therefore follows that for...

Consider the system of two blocks and a spring. The horizontal surface is frictionless, but there is static friction between the two blocks. The spring has force constant k = 150 N/m. The masses of the two blocks are m = 0.500 kg and M = 6.00 kg. You set the blocks into motion by releasing block M with the spring stretched a distance d from equilibrium. You start with small values of d, and then repeat with successively larger...

Consider two large bodies with identical heat capacities. The two bodies are initially at different temperatures, Th and Tc, respectively, with Th > Tc. They are then allowed to come into thermal contact and heat is transferred from one body to the other. The total entropy change for this thermodynamic process is Δ????? = Δ?ℎ + Δ?? = ?ℎ/?ℎ + ??/?? The first law of thermodynamics requires Δ????? = Δ?ℎ + Δ?? = ?ℎ + ?? = 0. Which means...

2. 10 points Consider a thermally isolated system consisting of two volumes of an ideal gas separated by a thermally conducting movable partition, which is initially fixed. Initially, the temperatures, pressures, and volumes of the two parts are P, V, T and 3P, 2V, and T respectively (see figure below). The partition is now allowed to move without gases mixing, until the equilibrium is reached. a) What is the change of the internal energy of the system after the equilibrium...

Q: Compare the assumptions of physician-centered and
collaborative communication. How is the caregiver’s role different
in each model? How is the patient’s role different?
Answer: Physical-centered communication involves the specialists
taking control of the conversation. They decide on the topics of
discussion and when to end the process. The patient responds to the
issues raised by the caregiver and acts accordingly. On the other
hand, Collaborative communication involves a...
