Thermal Energy, Temperature and Heat Answers
Answer: Heat flows from warm places to cooler places. Thus, heat is conducted into the cooler thermometer. The heat causes the molecules in the thermometer to vibrate more quickly. The increased kinetic energy of the atoms causes them to spread out and rise up the tube. The end result is that you can read your body temperature.
