Question
On a cool night you make your bed with a thin cotton sheet covered by a thick wool blanket. As you lay there all covered up, heat is leaving your body, flowing though the sheet and the blanket and into the air of the room. (The trick, of course, is to have enough blankets to make the flow of heat just right... If not enough flows you will be too hot and if too much flows you will be cold). Compare the amount of heat that flows though the sheet to the amount of heat that flows through the blanket. Question 6 options: More heat flows through sheet than through the blanket. More heat flows through blanket than through the sheet. The same amount of heat flows through sheet and through the blanket.
Explanation / Answer
More heat flows through sheet than through the blanket.
Because: The sheet is thin and heat conduction will be more through the thin sheet and less through the blanket as its thicker. After a thermal equilibrium is reached the temerature becomes uniform at both the ends.
