SCALE OF TEMPERATURE

Heat and temperature [SCALE OF TEMPERATURE]

CELSIUS, OR, CENTIGRADE, SCALE, FAHRENHEIT, SCALE, KELVIN, SCALE

SCALE OF TEMPERATURE:

There are three numerical scales for temperature measurement. • Celsius or Centigrade • Fahrenheit • Kelvin

1. CELSIUS OR CENTIGRADE SCALE:

Scale of temperature in which melting point of ice is marked as '0' zero and boiling point of water is marked as 100° and the interval between these two points is divided into 100 equal divisions is called Celsius scale.

2. FAHRENHEIT SCALE:

Scale of temperature in which melting point of ices is marked as 32 and boiling point of water is marked as 212 and the interval between these two points is divided into 180 equal divisions is called Fahrenheit scale.

3. KELVIN SCALE:

Scale of temperature in which point of lowest possible temperature corresponding to minimum molecular energy is marked as zero '0' and Boiling point of water is marked as 373 is called Kelvin or absolute scale.
