A metal sphere with a black surface and radius 30 min , is cooled to -73C (200K) and placed inside an enclosure at a temperature of 27^(@)C(300K) . Calculate the initial rate of temperature rise of the sphere, assuming the sphere is a black body. (Assume density of metal =8000 kg m^(-3) specific heat capacity of metal =400 J kg^(-1)K^(-1) , and Stefan constant =5.7xx10^(-8)Wm^(-2)K^(-4) ).

A copper cube with sides o flength 20 mm had its surface blackened. The cube is heated up to 500K and placed inside a room at a constant temperature of 300K. Calculate the initial rate of temperature fall of the cube, assuming it as a perfect black-body. (Stefan's constant = 5.7 xx 10^(-8) W//m(2) //K^(4) specific heat capacity of aluminium = 400 J //kg//K , density of aluminium = 7800 kg//m^(3) ) where A is the surface area of the cube, T_(1) is the temperature of the body, and T_(2) is the temperature of the enclosure.
