The blood plays an important role in removing heat from the body by bringing this heat directly to the surface where it can radiate away. nevertheless, this heat must still travel through the skin before it can radiate away. we shall assume that the blood is brought to the bottom layer of skin at a temperature of 37.0 ∘c and that the outer surface of the skin is at 30.1 ∘c . skin varies in thickness from 0.500 mm to a few millimeters on the palms and soles, so we shall assume an average thickness of 0.760 mm . a 165 lb , 6.00 ftperson has a surface area of about 2.00 m2 and loses heat at a net rate of 76.0 w while resting.
on the basis of our assumptions, what is the thermal conductivity of this person's skin?
answer in w/(k⋅m)

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
