A black body initially at `27^(@)C` is heated to `327^(@)C` is heated to `327^(@)C`. How many times is total heat emitted at the higher temperature than emitted at lower temperature ? What is the wavelength of the maximum energy radiation at the higher temperature ? Wien's constant `= 2.898 xx 10^(-3) mK`.
