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 black globe thermometer works?
Simply put, a black globe thermometer captures the raw temperature and solar radiation to calculate the "real feel" temperature of someone wearing a clothing or a uniform of some kind.
What instrument measures how hot or cold something is?
A thermometer is an instrument that measures cold and heat, together with temperature variations.

What instrument measures changes in temperature?
Temperatures are measured by instruments called thermometers.The instrument usually used to measure air temperature is the maximum-minimum thermometer. It consists of a U shaped tube with bulbs at each end and mercury at the bottom. Air heats or cools the bulbs causing the air inside to expand or contract, therefore pushing or pulling the mercury upwards or downwards.There are 3 types of thermometer: minimum thermometer, maximum thermometer,and the "Six's thermometer" -- these record the temperatures over a period of time.it says in my book that a thermometer measures air temperature
