Question 5 • Twilight Session 1 (Fall 26): Spanish I_Faria Polite

Which statement is an example of the law of conservation of energy?

Answer
A
A soccer ball eventually stops because its energy disappears.
B
When a light bulb is turned on, electrical energy is converted to light and heat.
C
An automobile engine burns gasoline to converts its chemical energy to electrical energy.

Explanation

The law of conservation of energy says energy is not created or destroyed; it changes from one form to another. In a light bulb, electrical energy is converted into light and heat, so the energy changes form rather than disappearing. Choice A incorrectly says energy disappears, and choice C does not accurately describe the energy conversion in an automobile engine.
