Question
The emissivity of the human skin is 97.0 percent. Use 35.0 °C for the skin temperature and approximate the human
body by a rectangular block with a height of 1.98 m, a width of 35.5 cm and a length of 26.5 cm.
Calculate the power emitted by the human body.
1.311x10³ W
You are correct.
Your receipt no. is 157-4629

Fortunately our environment radiates too. The human body absorbs this radiation with an absorbance of 97.0
percent, so we don't lose our internal energy so quickly. How much power do we absorb when we are in a room
where the temperature is 20.5 °C?
625.36W
Hint:
Use the Stefan-Boltzmann law again.
