Question

The diagram shows movement of thermal energy.

At bottom a fire has red curved lines labeled Y with arrowheads pointing upward to a pot. In the pot are red balls at the bottom and blue balls at the top. Black lines with arrowheads point upward from the red balls in the center of the pot, and black curved lines labeled W with arrowheads point downward from the blue balls along the sides of the pot. The handle of the pot is red near the pot and labeled X. The pot handle is held by a hand labeled Z.

In which areas of the diagram does conduction occur?

W and X
X and Z
Y and Z
Z and W

Answer 1

X and Z.

Explanation: X is heat conducted through the metal handle; Z is conduction between the hot handle and the hand (direct contact). W shows convection currents and Y is radiation/convection from the fire, not conduction.
