Looking at the picture, how would a solar cooker's temperature in the shade compare to a solar cooker's temperature in the sun after being left outside for 60 minutes?
Their temperatures would be the same for both solar cookers.
The solar cooker in the sun would heat up slower than the solar cooker in the shade
The solar cooker in the shade will heat up slower than the solar cooker in the sun
You cannot use solar cookers to cook food
