Insert description of apparatus, its component, what it is demonstrating. Leslie's cube (named after Sir John Leslie who experimented with radiant heat in 1804) consists of a cubical vessel with different sides - one of brass, the other two painted black and white, and another side painted with aluminum. When the cube is filled with boiling water, the radiation is greatest from the black side, and negligible from the shiny side.

Insert description of demonstration, how is the demonstration preformed. A Leslie's cube has four different surface areas. One side is black, one is white, one is aluminum and the last on is brass. Pour heat water into the cube. A reading of the heat radiation from the surfaces is made using a thermopile and an electrometer. You can show student that different surface can radiate the heat in different rate by using a thermopile and an electrometer. You can also show student by put another filter in between the thermopile and the cube to show variation.

Setup:

  1. Make sure that you have a boiling water.
  2. Hook the electric wires between the electrometer and a thermopile horn.

Cautions, Warnings, or Safety Concerns:

  1. Beware of hot water

Demonstration:

A Leslie's cube has four different surface areas. One side is black, one is white, one is aluminum and the last on is brass. Pour heat water into the cube. A reading of the heat radiation from the surfaces is made using a thermopile and an electrometer. You can show student that different surface can radiate the heat in different rate by using a thermopile and an electrometer. You can also show student by put another filter in between the thermopile and the cube to show variation.
