steps involved in measuring the temperature of boiling water

1. The thermometer that measures our body temperature is called a clinical thermometer.
 2. Hold the thermometer in  your hand and examine it carefully.
3. A clinical thermometer consists of a long, narrow, uniform glass tube. It has a bulb at one end. This bulb contains mercury. Outside the bulb, a small shining thread of mercury can be seen.
4.Thermometer should be washed before and after use, preferably with an
antiseptic solution.
5.􀂃 Ensure that before use the mercury level is below 35°C.
6.􀂃 Read the thermometer keeping the level of mercury along the line of sight.
7.􀂃 Handle the thermometer with care. If it hits against some hard object, it can break.
8.􀂃 Don’t hold the thermometer by the bulb while reading it.

This scale transformed the measurement of temperature into meaningful numbers. In the early years of the eighteenth century, Gabriel Fahrenheit (1686-1736) created the Fahrenheit scale. He set the freezing point of water at 32 degrees and the boiling point at 212 degrees.
