Solution

The correct option is B I-b, II-c, III-a
Solar cookers use the heat from the sun for cooking food. The functions of different components of the solar cooker are as follows:
1. Glass lid - covers the cover from top and creates greenhouse effect inside the cooker
2. Black painted surface - the surface of the solar cooker is painted black as black absorbs maximum solar energy. This increases the temperature inside the solar cooker.
3. Plane Mirror - plane mirror as a reflector and reflects more rays inside the cooker.
4. Concave mirror - concave mirrors are provided in the solar cookers for concentrating solar rays at one point. This increase the maximum temperature reached inside the solar cooker.
5. Insulator - an insulator is used to cover the solar cooker from outside so that the heat is not lost out of the cooker.

Q. Two students made box-type solar cookers separately. They both painted the insulated box with black colour from inside, the cooking pots were painted black from outside, and a plane mirror reflector was also attached. One of the students covered the solar cooker box with a transparent glass sheet but the other student covered the solar cooker box with a transparent plastic sheet. Which of the two solar cookers will be more efficient and why?
