Two containers, one at 305 K and the other at 295 K, are placed in contact with each other.

a. 1 J of heat flows from the hot container to the cold container. Find the change in entropy of the hot container and the cold container, and of the whole system (hot + cold container together). Does this process violate the second law of thermodynamics?

b. 1 J of heat flows from the cold container to the hot container. Find the change in entropy of the hot container and the cold container, and of the whole system (hot + cold container together). Does this process violate the second law of thermodynamics?

    One container holds 0.10 kg of water at 75 ∘C and is warmed to 95 ∘C by heating from contact with the other container. The other container, also holding 0.10 kg of water, cools from 25 ∘C to 5.0 ∘C. Specific heat of water is 4180 J/kg⋅∘C. Estimate the total change in entropy of two containers of water using the actual temperatures to determine the heat transferred to each container and the average temperatures to determine the change in entropy....

    Question 30 3 pts A heat engine operates between 200 K and 100 K. In each cycle it takes 100 J from the hot reservoir, loses 25 J to the cold reservoir, and does 85 J of work. This heat engine violates: o the second law but not the first law of thermodynamics o both the first and second laws of thermodynamics O the first law but not the second law of thermodynamics O neither the first law nor the...

    Suppose that there are two very large reservoirs of water, one at a temperature of 95.0 °C, and one at a temperature of 11.0 ℃. These reservoirs are brought into thermal contact long enough for 36330 J of heat to flow from the hot water to the cold water. Assume that the reservoirs are large enough so that the temperatures do not change significantly What is the total change in entropy resulting from this heat exchange between the hot water...

    Please Hill BUL YUUII.U., NM, DIU PASSWUIU WILL IULI 1. Which one is correct statement(s)? It is impossible that the entropy is decreased because it violates the thermodynamic second law. If a system undergoes a reversible adiabatic change of state, it is correct to say that the entropy of the system does not change.

    Two identical objects are in thermal contact. One is at a high temperature (T-hot) and the other is at a cool temperature (T-cool). Assume that this system is isolated, i.e. there is no interaction with the surroundings. Using the thermodynamic definition of entropy, explain why heat always flows from T-hot to T-cool, and never the other way around.
