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 enough information to decide, check the "not enough information" button in the last column. System Change AS O AS< 0 A few moles of carbon dioxide (CO2) gas. The carbon dioxide is compressed from a volume of 12.0 L to a volume of 8.0 L while the temperature is held constant at -2.0 °C. O AS = 0 OAS > 0 not enough information AS < 0 AS = 0 A few grams of liquid ammonia (NH3). The ammonia evaporates at a constant temperature of 29.0 °C. O AS > 0 not enough information AS < 0 O AS = 0 A few moles of carbon dioxide (CO2) gas. The carbon dioxide is cooled from 5.0 °C to 0.0 °C and is also compressed from a volume of 14.0 L to a volume of 3.0 L. O AS > 0 o not enough information x 6 ?

Answer 1

Entropy is degree of randomness or disorderness. Order of entropy is , solid<liquid<gas.

A) ∆S < 0

B) ∆S > 0

C) ∆S < 0
