Nora notices water droplets on the grass in the morning. It did not rain during the night. Which statement is true about this change of state?

Question

A. Mass was added to the water particles, resulting in deposition.

B. Energy was added to the water particles, resulting in evaporation.

C. Mass was removed from the water particles, resulting in sublimation.

D. Energy was removed from the water

Answer 1

The correct statement is:

D. Energy was removed from the water.

In this scenario, the water droplets on the grass in the morning are a result of condensation, which occurs when water vapor in the air loses energy (cools down) and changes from a gas to a liquid state. Hence, energy being removed from the water vapor in this case is what causes the droplets to form.
