B.1.11—Conduction question 1
[Maximum number: 2]
Describe the mechanism of heat transfer by conduction.
The diagram shows a wall separating the inside of a room from the outside. The temperature of the room is kept constant by a heater.
ALT 1 (in solids)
reference to particle/atomic vibrations
OR
kinetic energy transferred
via collisions
OR
between adjacent particles/atoms
ALT 2 (in metallic conductors)
reference to motion of electrons that collide with atoms/ions
