Answer to Question #188947 in Physics for Natalia Aisha Oloo

Question

A cylinder is made from a piece of aluminium fitted to a piece of wood. A strip of paper is

   glued around the middle. The paper is then heated over a Bunsen burner flame as shown on

   the diagram. After a while one end of the paper is noticeably more scorched than the other why this happens?

Answer 1

This happened because the thermal conductivity of these materials are different. Thus, different amount of heat from the burner flame was transferred to the paper.
