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?

Why will water boil at 96 Celsius?
it may be because of decrease in pressure.it can also be due to many other factors we define the boiling point as the temperature in which the molecules of the liquid leaves the surface and its pressure equals the atmospheric pressure so if we reduce pressure we can reduce boiling point
A device used to display the temperature?

If you have a fever of 100.1 and then take it again and it is 100.4 does that mean the thermometer is being faulty or does it mean you have a temp of 100.4?
How long between readings? If only a few seconds or minutes apart, split the difference and call it a 100.2 fever.

What is the formula between length of mercury level and temperature in degree celsius?
There is none. In the case of a thermometer, it will depend on the relative dimensions of the bulb and the capillary tube.
