Demonstrations

Identifier Title Demo Summary
T: H - 014 Thermal Conductivity Comparison

Rods of various metals have steel balls attached by wax.  One end of the rods are heated in the flame of a bunsen burner.  Over time, the balls on the rods drop off at different times.

3 ring stands with rods of different metals.  The rods have balls attached by wax.  All three rods converge over a bunsen burner
