What is the function of thermometer mercury?
The Mercury expands with temperature. Since expansion is linear over the normal range of a mercury-driven thermometer, the level of mercury within a little glass tube indicates the current temperature of the thermometer's immediate environment.
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 instrument measures how hot or cold something is?
A thermometer is an instrument that measures cold and heat, together with temperature variations.

What is mercury used for in a thermometer?
The thermal expansion of mercury is proportional and linear to temperature.
What is the mercury of the thermometer?

Why platinum is used in platinum resistance thermometer experiment?
Platinum resistance thermometer requires a small current to pass through it to determine its resistance at different temperatures. Platinum has a linear resistance-temperature relationship; we can use this method to find the resistance at different temperatures.
What are the types of thermometer?
Celsius, Fahrenheit, and Kelvin.
