DRAWBACKS OF CALORIC THEORY

One of the main problems with the caloric theory was its inability to explain the heat generated by friction,which was first noticed by Count Rum ford.Later on when it was proved that the sun rays reaches the earth after travelling through space and not through the material medium,caloric theory could not explain this way of heat transfer which was called heat Radiation.Hence caloric theory was rejected.
