The index of a thermometer is the scale or numerical reference used to indicate temperature readings. It can be in either Celsius or Fahrenheit, depending on the type of thermometer.
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
A minimum thermometer works by using a small column of mercury or alcohol that moves up as temperature increases and down as temperature decreases. A small steel index marker within the column remains at the lowest temperature reached, allowing users to see and record the minimum temperature.
The plural of thermometer is thermometers.
An ear thermometer is commonly referred to as a tympanic thermometer.
A glass bulb of a thermometer is the part at the bottom of the thermometer that contains mercury or colored alcohol that expands and contracts with temperature changes. This expansion and contraction of the liquid is what causes the thermometer to measure and display the temperature.
