Discover the drop in the blackbodys temperature

Reference no: EM13663867

A black body has a mass of 4.40 kg, specific heat of 2000 J/(kg · C°), surface area of0.198 m², emissivity 1.00, and initial temperature 95° C. The surroundings are at a temperature of 20.8° C. Discover the drop in the blackbody's temperature through a 4.70-minuteinterval that would result from heat loss with radiation only.
