Answer:
1) A solar cooker is a device which uses the energy of direct sunlight to heat or cook food materials.

3) Ideal cooking results when using a solar oven occur when the sun is bright and uninhibited by clouds, shadows etc.
4) Solar cooking is done by means of the suns UV rays.
5) A solar cooker lets the UV light rays in and then converts them to longer infrared light rays that cannot escape. Infrared radiation has the right energy to make the water, fat and protein molecules in food vibrate vigorously and heat up.
