A car uses the energy stored in the organic molecules of gasoline to propel the vehicle forward. However, not all the energy contained in the fuel molecules is used for propulsion; instead, some is lost as heat. In this scenario, entropy is ____, illustrating the ____ law of thermodynamics.
A)increasing; second
B)decreasing; second.
C)increasing; first
D)decreasing; second..
E)staying the same; second

Quizplus · Accepted Answer

Entropy is increasing because some of the energy stored in the fuel molecules is lost as heat, which is a less ordered form of energy. This illustrates the second law of thermodynamics, which states that in any energy transformation, the amount of useful energy decreases and the amount of entropy (disorder) increases.
