Answer 1

ANSWER :

The solar cooker which was covered with a plane glass slab would be more efficient. The glass lid allows the heat radiation from sun to enter the solar cooker but does not allow the reflected heat radiation to escape or go outside the box. Thus, heat trapped inside the box increases the temperature. Glass lid also reduces heat loss due to reflection.

❤Answer:

⭕A solar cooker covered by a plane glass slab will be more efficient.

⭕This is because glass slab does not allow the heat radiation to escape from the solar cooker and hence the temperature of the solar cooker with glass slab increases more than the temperature of the solar cooker which is left open.
