Mention the purpose of blackening the interior of a solar cooker |
|
Answer» Solar cookers are blackened from inside because black absorbs more heat from sun as compared to other colours. EXPLANATION: When more heat is absorbed by the blackened interiors, the food is cooked faster as more heat is absorbed inside the cooker. ... This helps in rapid increase of temperature inside the solar cooker The purpose of blackening the interior of a solar cooker is that the black surface absorbs more heat radiations of incident solar energy (about 98%) as compare to white or other light coloured surface. |
