Question

Draw a labelled diagram of the Solar cooker.

Accepted Answer

The solar cooker is a device that is used to cook food by using heat energy radiated from the sun. The following diagram represents a solar cooker.

A thick glass sheet covers the box and a plane mirror reflector is attached to the box. The food to be cooked is put in metal containers which are painted black from outside. These metal containers are then placed inside the solar cooker box and covered with a glass sheet. The solar cooker is kept in the sunshine. The radiation from the sun passes through the glass sheet. These are then absorbed by the black container. Once the sun’s heat rays enter the cooker box, then the glass sheet cover does not allow them to go back. The food cooked in a solar cooker does not lose its nutrients because food prepares at low temperatures.
