Principles of Solar Box Cooker Design

Which statement best states a central idea of the passage?

• Energy absorbed by dark materials in the solar box becomes trapped within the enclosed spaces.

• Reflectors are vital to the solar box because they cause higher cooker temperatures.

• Heat gain, loss, and storage are important factors in an efficient solar box.

• Glass solar boxes tend to radiate heat more efficiently than plastic.

Which statement represents a benefit of using heavy materials in a solar box?

• Things that are warm give off heat waves to their surroundings.

• Heat is lost when it travels through the molecules inside the box.

• The interior of a box containing more dense objects takes longer to heat.

• Dense materials, charged with heat, keep the box warm for a longer period.
