Question
For each system listed in the first column of the table below, decide (if possible) whether the change described in the second column will increase the entropy S of the system, decrease S, or leave S unchanged. If you don't have enouglh information to decide, check the "not enough information" button in the last column System Change The ammonia evaporates at a constant temperature of 34.0 °C A few grams of liquid ammonia (NH3) not enough information The carbon dioxide is cooled from 47.0 °C to 0.0 oC while the volume is held constant at 12.0 L. A few moles of carbon dioxide (CO2) gas not enough information The carbon dioxide is heated from -1.0 °C to 39.0 °C and also expands from a volume of 5.0 L to a volume of 15.0 L. A few moles of carbon dioxide (CO2) gas not enough informationExplanation / Answer
In the first part liquid is heated to form gas which increases the randomness hence S>0
For the second one, the gas is cooled which will decrease the randomness hence S<0
For the third part, the gas is heated which will increase the randomness of the gas molecules so S > 0.
