Question

In a box type solar cooker, the part which is responsible for producing greenhouse effect is:
1. Glass sheet
2. Black coating inside the box
3. The vessel in the cooker box
4. Plane mirror reflector

Answer 1

Correct Answer - Option 1 : Glass sheet

• The correct answer is Glass sheet
• A solar cooker is a device that uses the sun's energy to cook food.
• In a solar cooker, the glass sheet helps to keep the temperature inside the cooker warm.
• There is a box with transparent glass and reflectors to focus sunlight. The box is painted dark
• The glass sheet prevents the thermal radiation of the sunlight from going out of the box, causing a greenhouse effect.
• The outer box of the solar cooker is usually made of aluminium or fibre mixed plastic.
• The sunlight that falls on this glass reaches the cooker through the insulating material.
• These radiations directly increase the internal temperature and help the cooker to heat up quickly.
