Question

on a hot summer day, angelina and gael are having a picnic. angelina notices that there is liquid water on the outside of gaels cold soda can. which answer best explains what phase change has occurred and how the molecule arrangement has changed?
evaporation; molecules change from closely packed (liquid) to widely spaced (gas).
sublimation; molecules change from solid to gas without becoming liquid.
condensation; molecules change from widely spaced (gas) to closely packed (liquid).
freezing; molecules change from liquid to solid and become tightly packed.

Explanation:

Step1: Analyze the phase change process

The liquid water on the outside of the cold soda can is formed by the condensation of water vapor in the air. Condensation is the process where gas (water vapor, molecules widely spaced) changes to liquid (molecules closely packed).

Step2: Match with the given options

The option "Condensation; molecules change from widely spaced (gas) to closely packed (liquid)" correctly describes this phase - change process.

Answer:

Condensation; molecules change from widely spaced (gas) to closely packed (liquid)
