Heat Transfer Review

Which will most likely occur when raw egg is placed on black pavement on a hot, summer day?

• The pavement will conduct the heat and cook the egg.
• The egg will reflect the heat and make the pavement hotter underneath.
• The egg will absorb the heat  and leave the pavement hotter underneath.
• The pavement will absorb the heat from the egg, and the egg will stay raw.
