Explore a model of heat conduction in a solid.
Molecules with a temperature greater than absolute zero move. In a solid, the particles move but return to their average location within the solid.
Hotter molecules move faster than cooler ones. When a hotter particle collides with a neighboring cooler molecule, a portion of the heat transfers to the colder one, so it moves faster.
Step 1) Click "Setup."
Step 2) Click "Forever."
Step 3) Create a temperature gradient across the solid.
a) Click "Heat" to heat the molecules on the left.
b) Click "Cool" to remove heat from the particles on the right.
View the average temperature of the solid over time in the graph.
