WebIf the Earth were a black body then Earth’s surface albedo would be zero. If Earth were completely covered by ice and snow, then Earth’s surface albedo would be approximately 0.85. The same equation as was used for black-body earth is used to calculate the temperature of Earth with surface features but without an atmosphere. WebAlbedo of Earth is 0.29. (The Bond albedo should be used.) You will get T 4 = 3.846 × 10 26 ( 1 − 0.29) 16 π × ( 149, 000, 000, 000) 2 × ( 5.670373 × 10 − 8) = 4, 315, 325, 985 K …

With his law, Stefan also determined the temperature of the Sun's surface. He inferred from the data of Jacques-Louis Soret (1827–1890) that the energy flux density from the Sun is 29 times greater than the energy flux density of a certain warmed metal lamella (a thin plate). A round lamella was placed at such a distance from the measuring device that it would be seen at the same angular … WebHave students record the temperature right before they turn on the lamp (Time=0), entering the number into their data table. ...
