Question

which event is an example of vaporization?

a. the outside of a glass of ice water becomes moist.

b. frost forms on a blade of grass.

c. a cloud forms in the sky.

d. perspiration dries on a persons skin.

Explanation:

To determine the example of vaporization, we analyze each option:

• Option A: Moisture on the glass of ice water is condensation (gas to liquid), not vaporization.
• Option B: Frost formation is deposition (gas to solid), not vaporization.
• Option C: Cloud formation involves condensation (gas to liquid), not vaporization.
• Option D: Perspiration (liquid) drying on the skin means it changes to gas, which is vaporization (specifically evaporation, a type of vaporization).

Answer:

D. Perspiration dries on a person's skin.
