How does white paper effect cooking a marshmallow in solar oven?

A white paper does not have an effect on cooking a marshmallow in a solar oven. In fact, it would have a negative effect. White paper reflects light, and the purpose of a solar oven is to absorb light and convert it into heat.

A solar oven is a device that uses the energy from the sun to cook food. It is typically made from a cardboard box lined with reflective material, such as aluminum foil. The inside of the box is painted black, which helps to absorb heat. A clear piece of plastic wrap is placed over the opening of the box, which allows the sunlight in but prevents the heat from escaping.

To cook food in a solar oven, place the food in a black pot or container and place it inside the box. Close the box and point it towards the sun. The sunlight will heat the pot and cook the food.

A white paper would not be a good choice for lining a solar oven because it would reflect the light away from the food. This would make it take longer for the food to cook, or it might not cook at all.

Black is the best color for lining a solar oven because it absorbs the most light. Other dark colors, such as dark blue or green, can also be used.
