When a body is heated, which colour corresponds to high temperature
Open in App
Solution
The correct option is C white
When a body is heated then relation between colours and temperature is according to Prevost's theory of radiation which states that everybody is emitting radiant energy in all directions at a rate depending only on the nature oil surface and its temperature e.g., when a body is placed in an enclosure (furnace) it would acquire the temperature of furnace and seem white means radiate white light. So it becomes first dark and then white.
