To solve the question regarding the total entropy change for a system and its surroundings, we need to analyze the relationship between the type of process (exothermic or endothermic) and the entropy changes involved.1. Understanding En
The energy budget in the system of the earth, atmosphere and ocean conforms to the first law of thermodynamics, namely the law of conservation of energy, and it is balanced when the system is in a steady-state condition. However, the entropy budget following the second law of thermodynamics ...
In Eqs. (31) and (33), T represents the temperature of the boundary at which heat transfer takes place. If the system is selected such that it includes the immediate surroundings, the boundary temperature becomes the temperature of the surroundings. Therefore, one can use the surrounding ambien...
Note that the entropy change of this extended system is also zero since the state of air does not change at any point during the process. The difference between the two entropy generation rates is 0.150 W/K, and represents the entropy generation rate in the air layers on both sides of the...
In the limit of an ”infinite” number of steps (bottom), these work terms are identical, and both the system and surroundings (the “world”) are unchanged by the expansion-compression cycle. In all other cases the system (the gas) is restored to its initial state, but the surroundings...
Does the entropy of the system increase or decrease for each of the following? Explain. a. The evaporation of alcohol. b. The freezing of water. c. Dissolving NaCl in water. Does the entropy of the surroundings increase for spontaneous processes?

Charging a storage battery, freezing ice cubes, and the growth of living entities are examples. In each of these examples, the order of the system increases and the entropy decreases. If the combination of the system and its surroundings are considered, however, the overall net effect is ...
process in an isolated system (that is, one that does not exchangeheator work with its surroundings) always proceeds in the direction of increasing entropy. For example, the block of ice and the stove constitute two parts of an isolated system for which total entropy increases as the ice ...
The rigid walls guarantee that no work is done on the system, that is, there can be no change in the volume of the system and thus no P dV work by the surroundings. The process is called a free expansion because of the absence of any external work as gas moves into the evacuated ...
