SCALES OF TEMPERATURE | |||
| There are three main scales of temperature: 1) Centigrade or Celsius Scale 2) Kelvin Scale 3) Fahrenheit Scale | |||

CALORIC THEORY | |||
| Up to nineteenth century it was believed a weightless fluid called caloric which existed in every material body. Caloric is a hypothetical weightless fluid. Every object contains a specific amount of caloric. Hot bodies contains more caloric than the cold bodies. | |||
If caloric is added to a body, its temperature increases. When a body is broken, a large amount of caloric is released. | |||
FAILURE OF CALORIC THEORY | |||
| Caloric Theory has discarded now because it was unable to explain a number of thermodynamics process including production of heat by friction. | |||
