A solar cooker is made from a box with a glass lid covering the top of the box. The box has two layers: an outer insulating layer and an inner box painted black. A reflective panel is attached to one side of the box angled away from the glass cover. A cooking pot sits inside the solar cooker. Sunlight enters the solar cooker directly through the glass cover and indirectly by reflecting off of the reflective panel before entering the glass cover.
Which Two statements most accurately describe the flow of energy in a solar cooker?
A.
Thermal energy is transferred from the solar cooker's interior to the Sun.
B.
Heat flows from the solar cooker's cold surface to the cooler food inside.
C.
Thermal energy is transferred from the Sun to the solar cooker through radiation.
D.
The solar cooker transfers thermal energy from the cooler surroundings to the food.
E.
The solar cooker absorbs sunlight and converts it into thermal energy to heat the food.

The two statements that most accurately describe the flow of energy in a solar cooker are:
C. Thermal energy is transferred from the Sun to the solar cooker through radiation.
E. The solar cooker absorbs sunlight and converts it into thermal energy to heat the food.
These two statements effectively capture the energy transfer process that occurs in a solar cooker: the absorption of sunlight (radiation) and its conversion into thermal energy used for cooking.
