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.


What type of the thermometer would use to measure the temperature of ice?

You can use a digital or analog thermometer to measure the temperature of ice, but it's best to use a thermometer that can measure low temperatures accurately. A thermometer that measures from -50°C to 50°C would be suitable for measuring the temperature of ice.


What are the errors in the use of thermometer?

Some common errors in the use of a thermometer include not allowing it to equilibrate to the surrounding temperature before use, placing the tip in the mouth incorrectly or too quickly, and not properly cleaning and storing the thermometer after each use. Additionally, using a thermometer that is expired or damaged can also lead to inaccurate readings.
