A car uses the energy stored in the organic molecules of gasoline to propel the vehicle forward. In this scenario, the ____ energy in the gasoline is converted to ____ energy of motion, illustrating the ____ law of thermodynamics.
A)potential; chemical bond; second
B)chemical; activation; second
C)kinetic; potential; first
D)potential; kinetic; first
E)activation; kinetic; second

Question

Quizplus · Accepted Answer

The energy stored in gasoline is potential energy, which is converted to kinetic energy of motion when the car moves forward. This conversion illustrates the first law of thermodynamics, which states that energy cannot be created or destroyed, only transferred or transformed. Choice A is incorrect because chemical bond energy is a type of potential energy. Choice B is incorrect because activation energy is the energy needed to start a chemical reaction, not the energy stored in gasoline. Choice C is incorrect because kinetic energy is the energy of motion, not potential energy. Choice E is incorrect because activation energy is not relevant to the conversion of energy in gasoline to motion in a car.
