- Under which condition does the combined entropy of two interacting systems decrease? Group of answer choices When there is no heat flow (meaning the two systems are isolated) When there is no work done When there is no change in internal energy NeverYou are holding a 500-g dark chocolate bar, and then the chocolate starts to melt at 45 degrees C. What is the change in entropy? (Note: The latent heat of fusion of chocolate Lf = 1.5 x 10^5 J/kg. Calculate first the heat needed to melt the chocolate using the formula Q = mL^f, where Q is the amount of heat needed to melt the chocolate, m is the mass of the chocolate, and Lf is the latent heat of fusion of chocolate.)When 2.1 kg of water at 12.3 °C is mixed with 3.7 kg of water at 39.7 °C in a well-insulated container, what is the change in entropy of the system?

- Which statement regarding entropy is false? A child builds a tower from a pile of blocks. The entropy of the blocks increases. A layer of salt then a layer of pepper are placed in a jar then shaken. The entropy of the salt and pepper increases. Gasoline is burned in a car engine to form exhaust. The entropy of the gasoline increases. A candle burns to heat the surrounding air. The entropy of the candle and surrounding air increases.Choose the correct statements. a. The equilibrium state is the macrostate with the smallest number of microstates. b. The equilibrium state is the macrostate with the largest number of microstates. c. The equilibrium state of an isolated system has minimum entropy. d. The equilibrium state of an isolated system has maximum entropy. e. Isolated systems always have maximum entropy.Write TRUE if the statement is correct and change the underlined word/words if incorrect. The second law of thermodynamics emphasizes that the entropy of an isolated system is constant.
- Zeroth law of thermodynamics can be derived. It is not based on observation. True or False? a) True b) FalsePlease describe to me the laws of thermodynamics. There are a certain number of them and therefore you must have all of them. Each should be labeled with it's number. For instance "The First Law of thermodynamics says that..."
