Here's why:

* Temperature and Molecular Motion: Temperature is a measure of the average kinetic energy of molecules. Kinetic energy is the energy of motion. The higher the temperature, the faster the molecules move.

* Hot Soup vs. Iced Lemonade: Hot soup has a higher temperature than iced lemonade. This means the water molecules in the hot soup have more kinetic energy and are moving faster than the water molecules in the iced lemonade.
