A hiker is wearing wool clothing of 0.50-cm thickness to keep warm. Her skin temperature is 35C
Question:
(a) If the thermal conductivity of wool is 0.040 W/(m ∙ K), what is the rate of heat conduction through her clothing?
(b) If the hiker is caught in a rainstorm, the thermal conductivity of the soaked wool increases to 0.60 W/(m ∙ K) (that of water). Now what is the rate of heat conduction?

Conduction heat transfer is the transfer of heat through matter (i.e., solids, liquids, or gases) without bulk motion of the matter. In another ward, conduction is the transfer of energy from the more energetic to less energetic particles of a substance due to interaction between the particles. Conduction heat transfer in gases and liquids is due to the collisions and diffusion of the molecules during their random motion.
