Linear expansion of a metal rod

Heat metal rods of different material: ΔL = αL₀ΔT is read on a dial gauge; find α, see expansion gaps and how a bimetallic strip bends.

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: thermal expansion · linear expansion · coefficient · bimetallic strip
