Question

a rug sits in a sunny place on the floor for a long time. kiara thinks that light from the sun can cause the rug’s color to fade over time. can light from the sun cause the rug’s color to fade?
options:
no. light is not a physical thing, so it cannot change physical things like rugs.
no. light can only change things by warming them up, so it cannot cause the rug’s color to fade.
yes. the rug can take in energy from the light, causing the rug’s color to fade.
yes. light from the sun can pull energy out of the rug, causing the rug’s

Explanation:

To determine if sunlight can fade a rug's color, we analyze the options:

• First option is wrong: Light is a form of energy (electromagnetic radiation) and is physical, so it can interact with matter.
• Second option is wrong: Light can cause chemical changes (like photodegradation in dyes) beyond just heating.
• Third option is correct: Sunlight (light) carries energy; when the rug absorbs this energy, it can break down dye molecules (photodegradation), leading to color fading.
• Fourth option is incomplete and incorrect in reasoning (light doesn’t “pull energy” but transfers its own energy to the rug).

Answer:

Yes. The rug can take in energy from the light, causing the rug’s color to fade.
