Thermometers measure temperature by using liquids (like Mercury or alcohol) that expand and contract based on temperature changes. As the liquid expands, it rises in a narrow tube to indicate the temperature. The scale on the thermometer is calibrated to show the temperature based on how much the liquid expands or contracts.
