The thermometer consists of a very fine glass tube having a very small bore and is called capillary tube. At one end of capillary tube a very thin glass bulb is provided. The bulb is filled with Mercury( most of the times) or alcohol The other end of capillary tube is sealed. The capillary tube is protected by a thick glass tube called stem. On the stem are made markings. These markings are called graduations or degrees.

Describe how a thermometer is read?
A thermometer is read by looking at the level where the liquid inside the tube stops rising. This level corresponds to the temperature measurement indicated on the scale of the thermometer. The temperature can be read in degrees Celsius or Fahrenheit depending on the type of thermometer.
How do you tell how hot or cold something is?
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.
How does a Cardboard Thermometer work?
A cardboard thermometer works by using a temperature-sensitive chemical that changes color in response to temperature changes. The chemical is typically housed in a sealed glass tube and as the temperature changes, the chemical expands or contracts, causing the color to indicate the temperature. The cardboard backing provides structure and stability to the thermometer.
