Temperature is one of the fundamental (base) quantities.
During the day we feel hot, but cool at night.
Fire is hot, but ice is cold.
A hot object is said to have high temperature, but a cold object has low
temperature.
Thus temperature shows the degree of hotness and coldness
of an object.
Your palm can feel the hotness or coldness of a thing. But can you use
it to measure temperature?
. The common measuring tool for
temperature is a thermometer.
A thermometer consists of a long glass tube with a narrow column, called capillary pipe, containing liquid, alcohol or
mercury. But, the upper part is vacuum.
The kinds of temperature scales : Fahrenheit, Celsius , Reamur and Kelvin.
There are four commonly used temperature scales in existence they are:
Celsius: The celcius scale is defined such that the freezing point of water is 0°C and the boiling point of water is at 100°C. Absolute zero occurs at –273.15°C.
Kelvin: The kelvin scale is the celcius scale offset such that absolute zero occurs at 0 K. This means water freezes at 273 K and boils at 373K.
Fahrenheit: The fahrenheit scale is defined such that the freezing point of water is 32°F and the boiling point of water is at 212°F. Absolute zero occurs at –460°F.
Reamur: The reamur scale is defined such that the freezing point of water is 0°R and the boiling point of water is at 80°R. Absolute zero occurs at –218,4 °R.
