Which part of the solar cooker is responsible for green house effect?

(A) Coating with black colour inside the box

(B) Mirror

(C) Glass sheet

(D) Outer cover of the solar cooker

Answers (1)

Answer : (C) Glass sheet

Glass sheet/plate traps infrared radiations from sunlight and does not allow heat to escape. Solar cookers are covered with a glass plate. Thus this glass plate provides greenhouse effect.

Under identical conditions, a black surface absorbs more heat as compared to a white or a reflecting surface. Solar cookers achieve a higher temperature by using mirrors to focus the rays of the Sun.

Therefore option (C) is correct
