Problem: A student is studying in a room that is 20 ?C. The average skin temperature of a human body is around 34 ?C, but clothing provides insulation. Hence, the surface temperature of the student's clothing is about 28 ?C. In this quiet setting, the student and room are in thermal equilibrium.

Required:

Question 1: At 28 ?C, the student emits infrared blackbody radiation with an emissivity e ≈ 1. If the student's body has a surface area of 1.5 m2, calculate the student's radiated power.

Question 2: At 20 ?C, the room's walls also emit infrared radiation with an emissivity e ≈ 1. Calculate the power absorbed by the student's body due to the room's blackbody radiation.

Question 3: What is the student's net radiated power (emitted minus absorbed)? Compare this to a typical food diet of 1,900 kcal/day.
