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.
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.
White light minus magenta light would appear cyan in color. Cyan is the complementary color to magenta, so when magenta light is subtracted from white light, the remaining color is cyan.
White light minus yellow light appears as a bluish color, due to the absence of yellow light in the spectrum. This phenomenon is known as color subtraction or color mixture.
What is the color of light where the thermometer is located?
Mercury in a Mercury thermometer is typically silver in color.
The color located between red and yellow in a rainbow is orange. It is created by combining red and yellow light wavelengths.
The cones, located in the retina, detect color.
The color located between green and indigo in the visible spectrum is cyan.
A thermometer and light meter are the most useful when measuring two environmental changes.
temperature warning light
The color located between green and indigo is blue.
The thermometer of most cars is located at the front of the engine compartment. This allows it to pull in air from the outside to more accurately measure temperature.

A blue-tipped thermometer is commonly used for axillary temperature readings.
.... by measurement with an device designed for one particular property: balance for mass, thermometer for temperature, ruler for length, spectrophotometer for color, photometer for light, etc.
