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 the cooker 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:

The glass cover allows sunlight to pass through and prevents heat loss, making the cooker more effective.

Answer 1

The Correct Option is B

The glass cover of a box-type solar cooker helps to trap the heat inside and prevent it from escaping, thus reducing heat loss due to radiation. This is important for efficient cooking.
