Please explain Heat Transfer and Changes in the Entropy of the Surroundings. Below are key questions. 1. Know and understand that the entropy change for the universe is defined in terms of the entropy change for the system and the entropy change for the surroundings. 2 .Know that a process in which the system’s entropy decreases can still be spontaneous depending on the degree to which the surroundings’ entropy changes. 3. Know and understand that an exothermic process increases the...
