Chapter 42, Problem 5RQ
As the temperature differential across a panel increases,
A. the rate of heat transfer through the panel will increase.
B. the rate of heat transfer through the panel will decrease.

Why do we feel colder when we touch the metal spoon than when we touch the wooden one? a. Since metals usually have a lower heat capacity than non-metals, the metal spoon loose more heat to the room and consequently has a lower temperature b. Metals release heat faster than non-metals because of their higher thermal conductivity c. This is merely psychological since we are conditioned to think of metals as “cold” d.
