Question

The upper part of a box-type solar cooker has a glass cover. The reason for this is:

• A. To see whether the food kept inside is being cooked or not
• B. To prevent loss of heat due to radiation
• C. To prevent the passage of dust into the box
• D. None of these

Hint:

Solar cookers use the greenhouse effect to trap heat and cook food efficiently.

Answer 1

The Correct Option is A

A glass cover in a solar cooker allows sunlight to enter while trapping heat inside, and it also enables users to check the cooking process without opening the lid. Thus, the correct answer is \( \mathbf{(A) \text{To see whether the food kept inside is being cooked or not}} \).
