Answers

A solar cooker is a cooking utensil which utilizes the energy from direct sunlight to heat, to cook or aseptic drink and other food substances. Most of the solar cookers currently in use are adequately economic and low tech appliances. While some are as effective or as high priced as conventional stoves which can cook for hundreds of people.

Complete step by step answer

The inside surface of a solar cooker is painted black because the solar cookers have to focus the sunlight onto a recipient such as a cooking pan. The inter connection between the light energy and the recipient material transforms light energy into heat energy. This transformation is boosted by using materials that direct and preserve heat. Pots and pans that are used on solar cookers should be bleached black in colour to boost the absorption rate of heat. Black surfaces are outstanding absorbers of radiation and help in imprisoning more heat inside a solar cooker and therefore enhancing the coherence of the solar cooker.

Therefore, inside the surface of a solar cooker it is painted black in colour because Black surfaces are a good conductor of radiation which absorbs more heat.
