Conduction, Convection, and Radiation

Heat Conduction of Metals

[M | t+ | —]
The ends of four metal rods are placed in boiling water; indicators at the other ends show markedly different heat conduction.

Convection Cell

[S/M | t+ | ★★★]
A temperature gradient is applied to a two-dimensional cell filled with rheoscopic fluid; beautiful convection currents are observed.

Black Body Radiation Spectrum

[L | t+ | —]
Prism shows spectrum of 1 kW lantern projector operated with a Variac.

Black Body Radiation Oven

[L | t+ | ★★★]
Clay and iron objects within a kiln; all radiate with same color when at thermal equilibrium.
