Answer»

Answer:

When an object is made hot, the atoms inside the object become thermally excited. If the object does not melt, the outer orbit electrons of the atoms jump to higher ENERGY level due to the SUPPLIED energy. The electrons on these higher energy levels are not STABLE, they again fall back to lower energy levels. While falling from higher to lower energy levels, the electrons release their extra energy in a FORM of photons. These photons are then emitted from the surface of the object in the form of electromagnetic RADIATION.
