Heat conduction through a rod

A rod with hot and cold ends: watch the temperature profile evolve to a steady linear gradient, Q = kAΔT/L, compare materials and rods in series.

About this experiment

What you do in the lab

Change the controls and watch the physics behave in real time in 3D. Live readouts and graphs show the numbers behind it, and the Learn tab has the theory, procedure, observations and viva questions. Works on a phone or a laptop, in English and Hindi.

Topics: conduction · thermal conductivity · steady state · temperature gradient
