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. | |||
