a) Assuming your skin temperature is 97.2 F and the temperature of your surroundings is 60,0 F, determine the length of time in minutes required for you to radiate away the energy gained by eating a 430 kJ apple. Let the emissivity of your skin be 0.9 and its area be 1.22 m. [Answer in 2 significant figures] NEW PROBLEM * b) [10 points] It is desired to just able to slip the 16.0 mm diameter glass marble through an aluminum washer. At 20.0 C, the inner diameter of the washer is 15.98 mm. To what temperature should the aluminum washer be heated for the marble just able to slip through. The marble remains at 20.0C. Qaluminum = 2.3x10-5 C-1; and glass = 2.7x10-5 C-1 [Answer in 2 significant figures] a) Assuming your skin temperature is 97.2 F and the temperature of your surroundings is 60,0 F, determine the length of time in minutes required for you to radiate away the energy gained by eating a 430 kJ apple.
