Question

malachi uses some glue to fix a broken plate. he puts the glue under a desk lamp but the glue doesn’t dry. then he puts the glue out in the sun and it dries. why does light from the sun dry the glue when light from the desk lamp does not?

because the glue can take in energy from the light from the sun but not from the light from the lamp.

because light from the sun pulls energy out of the glue and light from the desk lamp does not.

because the sun gives off a type of light that carries energy, and light from the desk lamp does not.

because light from the sun carries heat molecules, and light from the desk lamp does not.

Explanation:

To solve this, we analyze each option:

• Option 1: Glue drying involves absorbing energy (like heat) from light. Sunlight has more energy (including heat - related energy) that the glue can absorb, while the desk lamp's light may not provide enough or the right type. This makes sense.
• Option 2: Light doesn't "pull energy out" to dry glue; drying requires energy input (absorption), so this is incorrect.
• Option 3: All light carries energy (electromagnetic energy), so saying desk lamp light has no energy is wrong.
• Option 4: Light doesn't carry "heat molecules"—heat is related to energy transfer, and light is electromagnetic radiation. This is a misconcept.

So the correct option is the first one.

Answer:

A. Because the glue can take in energy from the light from the sun but not from the light from the lamp.
