You might wonder and think what do thermometers measure to provide the temperature reading? Well here it is, the material transmits heat energy to the mercury when the tip of the mercury thermometer comes into contact with the substance being measured. The mercury then becomes a liquid, swells, and starts to ascend the tube. You can take a temperature reading at the point where the mercury stops on the scale.
