Level of liquid or gas in the tube â The appropriate volume of liquid or gas in the tube depends on the expansion coefficient of the substance used, the area of the capillary and the range of temperature required. Bimetal or bi-metallic thermometers use a bimetal spring as the temperature-sensing element.
The glass tube of a thermometer usually contains mercury. Mercury is perfect to test temperature because it changes from a solid to liquid very easily. When the metal tip of the thermometer comes into contact with the material it is testing, it conducts heat energy to the mercury.t takes only 30 seconds for a digital thermometer to give you a reading because the heat-sensitive tip is able to accurately tell the computer chip inside what the temperature is. Your normal body temperature would be 98.6 Â°F on the Fahrenheit scale.
