Question

A small cup of water is left out on the counter. Three days later, the water is gone. Which phase change describes what has occurred?

Melting
Sublimation
Evaporation
Condensation

Answer 1

I believe that it should be water evaporation

Answer 2

Answer:

The correct answer is: evaporation.

Explanation:

Hi!

Let's solve this!

Let's analyze each of the options:

melting: melts when it goes from solid to liquid.

Sublimation: it is the change of state from solid to gaseous directly.

condensation: it is the change of state of gas to liquid.

evaporation: it is the change of state that passes from liquid to gaseous.

In this case, we conclude that the water passed from liquid to gas state, so the process is evaporation.
