" A body at .....,emits no heat energy."

A body does not emit heat energy at

A black body at 20000 K, emits maximum energy at a wavelength of 1.56 mu m . At what temperature will it emit maximum energy at a wavelength of 1.8 mu m ?

Is it possible to heat a body without providing heat energy? How?

The rectangular surface area 12cm xx 6cm of a black body at a temperature of 127^(@)C , emits heat energy at the rate of Q units per second. If the length and breadth of the surface area are each reduced to half of its initial value and the temperature is increased to 327^(@)C , then the rate of emission of heat energy will be

A black body at 1500K emits maximum energy of wavlength 20000 Å . If sun emits maximum energy of wavelength 5500Å , what would be the temperature of sun.
