We 3.5 Absorption du rayonnement thermique

Principle

A polished and a black beaker are heated by radiation. Instead of solar radiation a bright flame located in front of the two beakers is used.
Both beakers are filled with air since the heat capacity of water is very large and it would be too slowly heated.

Benefits

  • Real ...
