Topics covered:
- Thermal radiation
- Emissivity
- Kirchhoff's Law
- Leslie's Cube
- Black body and gray body
Principles and objectives:
Thermal radiation can be measured on all surfaces as long as their temperature differs from that of the environment. Therefore, the hotter an object is, the more radiation it emits. The color of the surface also influences behavior: dark surfaces emit more thermal radiation than light surfaces. This didactic set is used to:
Determine and compare the emissivity of the four faces of a Leslie's cube at a constant temperature. The thermal radiation of the cube filled with boiling water is measured using a Moll thermopile.
The same study as before but based on temperature.
Record the thermoelectric voltage as a function of temperature for each face of the cube and validate Kirchhoff's Law on thermal radiation for the Leslie's cube used.
