1 Thermal Properties Of Matter
Parallel rays of light of intensity I=912 Wm-2 are incident on a spherical block body kept in surroundings of temperature 300 K Take Stefan constant σ=5.7×10-8 Wm-2 K-4 and assume that energy exchange with the surroundings is only through radiation. The final steady state temperature of the black body is close to
