Temperature Scales.
a.
Celsius. Celsius or centigrade is a temperature scale that registers the freezing point of water as 0°C and the
boiling point as 100°C under normal atmospheric pressure. Celsius is the official designation for this scale, but centigrade
is commonly used.
b.
Fahrenheit. Fahrenheit is a temperature scale that registers the freezing point commonly used. of water as
32°F and the boiling point as 212°F under normal atmospheric pressure.
c.
Kelvin. Kelvin is a temperature scale on which the degree intervals are equal to those of the Celsius scale.
On the Kelvin temperature scale the freezing point of water is 273.16°K and the boiling point is 373.16°K.
