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.
