Assume a coffee mug is completely filled with creamed coffee. Assume both of their temperatures are initially at 160 Fahrenheit and the atmospheric temperature is 50 Fahrenheit. How long will it take the coffee mug to reach 60 F due to radiation ignoring the transfer of heat to each other by conduction? (Take the density of the coffee to be 1.2 g/cm3 , its specific heat to be .90 cal/g.C and the mass of the cup to be 250 grams and its specific heat to be .3 cal/g.C. Also, take the emissivity of the creamed coffee to be .4)
