Question

Which part of the solar cooker is responsible for greenhouse effect?
A. coating with black colour inside the box
B. Mirror
C. Glass sheet
D. Outer cover of the solar cooker

Answer 1

Hint: The sun rays pass through the glass sheet which is used as a cover in the solar cooker and these sun rays are absorbed inside the cooker. It traps more rays of the sun, thus it is helpful in heating the food item. But the heat captured inside the glass sheet is responsible for generating greenhouse gases.

Complete step by step solution:
In the solar cooker the same process occurs, the sun rays that are reflected by the mirror are trapped in the solar cooker by the glass plate (greenhouse effect) and are used to heat the food. The transparent glass sheet over the cooker is responsible for the greenhouse effect in a solar cooker. Infrared radiation emitted by sunlight is used in heating up a solar cooker. The Glass sheet is responsible for greenhouse gases because it captures the heat inside the solar cooker.

Hence, the correct option is (C).

Additional Information: There are four basic types of solar cooker: panel cooker, box cooker (sometimes called box ovens), parabolic cooker and tube cooker.

Note: When the heat from the sun goes inside the solar cooker, it gets trapped inside the cooker. These trapped heat rays are unable to escape into the environment due to the glass cover provided to the cooker, thus enabling it to cook food.
