A) 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 1.84 m, a width of 30.0 cm and a length of 24.0 cm. Calculate the power emitted by the human body.
B) 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 23.5 °C?
C) How much energy does our body lose in one second?

Consider a cell of a teratoma and a healthy human epithelial
(skin) cell. Now consider the DNA and the three types of RNA (mRNA,
tRNA, and rRNA) found in both. For each of these (DNA, mRNA, tRNA,
and rRNA), compare what you would expect to find in both a teratoma
and a healthy cell. Would they be the same, or different, or both?
Provide examples and explain clearly.

The average resistivity of the human body (apart from surface
resistance of the skin) is about 5.0 Ω⋅mΩ⋅m. The conducting path
between the right and left hands can be approximated as a cylinder
1.6 mm long and 0.10 mm in diameter. The skin resistance can be
made negligible by soaking the hands in salt water. If skin
resistance is negligible, what potential difference between the
hands is needed for a lethal shock current of 100 mAmA? (Your

Exactly 18.6 mL of water at 35.0 °C are added to a hot iron
skillet. All of the water is converted into steam at 100.0°C. The
mass of the pan is 1.50 kg and the molar heat capacity of iron is
25.19 J/(mol·°C). What is the temperature change of the
skillet?
