Question

question 3.
in which example is solar energy being transformed into chemical energy?
a. a flashlight using a battery to make light
b. sunlight melting glacial ice
c. a plant using sunlight to make food
d. starting a fire with gasoline

Explanation:

• Option A: A flashlight using a battery involves chemical - electrical - light energy transformation, not solar - chemical.
• Option B: Sunlight melting glacial ice is a solar - thermal (heat) energy transformation.
• Option C: In photosynthesis, plants use sunlight (solar energy) to convert carbon dioxide and water into glucose (chemical energy).
• Option D: Starting a fire with gasoline is a chemical - thermal and light energy transformation (from the stored chemical energy in gasoline, not directly from solar energy in this process).

Answer:

C. a plant using sunlight to make food
