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 measures temperature which is not a thermometer?
By definition, something that measures temperature is a thermometer.'Thermo-' means 'to do with heat''Meter' means 'to measure'Thermometer literally means 'A measurer of temperature'You might mean a thermostat which is a special kind of thermometer which alterers its behaviour depending on the temperature. Thermostats are used in heating systems to prevent it from getting too hot.
What is a thermo meter used for?
A thermometer is used to measure temperature in various environments or substances. It helps in monitoring body temperature, checking food temperatures for cooking, and gauging the temperature in industrial processes.
What does it mean when a thermometer says L?
When a thermometer displays "L", it typically indicates that the temperature reading is below the thermometer's lower limit or range of measurement. This could be due to the temperature being too low for the thermometer to accurately detect.
What do you mean a range of a thermometer?
The range of a thermometer refers to the range of temperatures it can measure accurately. For example, a thermometer with a range of -20°C to 100°C can accurately measure temperatures within that range, but may not be accurate outside of it.

What does prefix thermo in thermosphere mean?
The prefix "thermo" in thermosphere refers to heat or temperature. The thermosphere is the layer of the Earth's atmosphere where temperatures increase with altitude due to the absorption of solar radiation.
