    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.
