To study the structure and working of a solar cooker and/or water heater.
Activity is done for understanding how the solar equipments are insulated and how does maximum heat absorption is ensured.

Property : A black surface absorbs more heat.
Structure :
`rarr` It consists of an insulated metal box or a wooden box which is painted black from inside.
`rarr` The box has a thick glass sheet as a cover over the box.
`rarr` A plane or concave mirror is attached to the box that acts as a reflector.
`rarr` Mirror focuses the rays of the sun into the box.
What temperature is achieved in solar cooker/solar water heater ?

Text Solution

Verified by Experts

Typically solar cooker is designed to achieve `65^(@)C(150^(@)F)` temperature.
The temperature of water in the solar water heater is determined by the combination of collector area and the tank capacity. Typically it would be `50-60^(@)C`, which is much hotter than the bathing water temperature (around `40^(@)C`).
