Question

1. a rug sits in a sunny place on the floor for a long time. kiara thinks that light from the sun can cause the rugs color to fade over time. can light from the sun cause the rugs color to fade?

a no. light is not a physical thing, so it cannot change physical things like rugs.
b no. light can only change things by warming them up, so it cannot cause the rugs color to fade.
c yes. the rug can take in energy from the light, causing the rugs color to fade.
d yes. light from the sun can pull energy out of the rug, causing the rugs color to fade.

Explanation:

Light from the sun is a form of energy. When light (especially ultraviolet light) interacts with the rug, it can cause chemical changes in the dyes or materials of the rug. This is a physical - chemical process where the energy from the light is absorbed by the rug's components. Option a is incorrect because light is a form of energy (a physical thing). Option b is wrong as light can cause changes not just by warming (for example, through photochemical reactions). Option c is also incorrect as it's not about the rug "taking in energy from the light" in the way described. Option d is correct as light (from the sun) can cause energy - related changes (like fading due to photodegradation) in the rug.

Answer:

d. Yes. Light from the sun can pull energy out of the rug, causing the rug's color to fade.
