THERMAL EXPANSION OF A LIQUID<br />
Temperature Relates to Kinetic Energy of Atoms<br />
Atoms move faster at higher temperatures. The liquid inside a thermometer expands when placed in proximity to heat, indicating a higher temperature. When the thermometer is placed in ice water, the liquid inside the thermometer contracts as it cools.
