- 17. Multiple Choice
Imagine the particles in hot chocolate and those in a Coke. Which one are moving faster?
The particles in the hot chocolate are moving faster because the hot chocolate is at a higher temperature.
The particles in the Coke are moving faster because the Coke is at a colder temperature.
The are moving at the same speed because they are both liquids.
The particles are not moving in either liquid unless someone is shaking the cup.

Why does the mirror in the bathroom fog up when you take a hot shower?
The water vapor gas from the shower touches the cold mirror, loses energy and condenses to becomes liquid water on the mirror.
The water vapor from the shower touches the cold mirror, gains energy and starts moving even faster.
Liquid that was behind the mirror moves to the front of the mirror.
The water vapor gas experiences sublimation when it touches the mirror.
