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.
Does a thermometer use kinetic energy?
A thermometer measures temperature by detecting the thermal energy of the substance it is in contact with, which is related to the kinetic energy of its molecules. So, in a way, a thermometer indirectly utilizes kinetic energy to provide temperature readings.
How was the thermometer invented?
Various people have credited the invention of the thermometer but the thermometer was not a single invention, however, but a development. Related Link:http://en.wikipedia.org/wiki/Thermometer
What does the 'thermo' in thermometer mean?
The prefix 'thermo' in thermometer comes from the Greek word "thermos," meaning hot or heat. This indicates that a thermometer is a device used to measure temperature, which is a reflection of heat energy.
What is the plural of thermometer?
The plural of thermometer is thermometers.
How was the thermometer discovered?
Wikipedia explains it well. See "Thermometer" in "related links" for a link to the wikipedia page.
