A student constructed a box type solar cooker. He found that it is not working efficiently. What could this be due to? Give any four possible mistakes in the construction and operation of the solar cooker. What can maximum temperature ordinarily be reached inside a solar cooker?
there can be some basic mistakes which can be done by the student. Once the following mistakes are corrected, his/her solar cooker will start working efficiently-
1) he/she might not have painted the cooker black. Black color is the best absorber of heat, thus painting it black will give better results.
2) he/she might not have covered the solar cooker with a glass cover. This glass cover traps the heat inside the cooker thus increasing the temperature.
3) while constructing a solar cooker one must place spherical reflectors inside the cooker so that they can converge the light at specific point thus giving a better result.
4) the sides of solar cooker must be covered with some thermally insulating layer to reduce the heat loss.
