You are presented with the question "What results in changing from a gas into a liquid by reducing heat energy?" and the following answer choices: 
- exposure to cold
 - degrees celcius
 - molecules joining together
 - rain or sun shine
 - Warm air moving into cold air
 - molecules separating
 - molecules becoming nothing
 - molecules exploding

Now knowing that condensing means changing from a gas into a liquid by reducing heat energy and condensation involves molecules joining together with the release of water, choose the best answer.
