Copper is known for its excellent heat conductivity, resulting in even heating across the surface. This is why copper cookware is popular among chefs for its ability to distribute heat quickly and uniformly.
A dark, rough surface will absorb the most heat energy because it absorbs more sunlight and the rough texture increases the surface area for absorption. Smooth, light-colored surfaces reflect more sunlight and absorb less heat energy.
Foil is a good conductor of heat, so heat transfer by conduction occurs when using foil. When foil comes into direct contact with a hot surface or food, it quickly conducts heat away, helping to cook or heat food more rapidly.
The type of surface of an object affects how it radiates and absorbs heat energy by influencing its albedo, emissivity, and conductivity. Objects with darker colors absorb more heat because they have higher absorption rates (lower albedo), while objects with rough textures tend to have higher emissivity, allowing them to efficiently emit heat. Additionally, materials with high thermal conductivity transfer heat more easily, affecting how quickly they absorb or release thermal energy.
Radiation is the type of body heat loss characterized by heat transfer from the surface of one object to the surface of another object without actual contact. This occurs through electromagnetic waves emitted by the warmer object and absorbed by the cooler object.

Infrared light delivers most of the heat from the sun to the Earth. This type of light has longer wavelengths than visible light and is able to penetrate the Earth's atmosphere more effectively, transferring its energy into heat when absorbed by surfaces on the Earth's surface.

Surfaces can be heated using various methods such as conduction (direct contact with a heat source), convection (heating air or fluid around the surface), or radiation (emitting heat energy). The most suitable method depends on the type of surface and the desired heating rate.
A light-colored, smooth surface like white concrete or aluminum reflects heat energy by redirecting it away rather than absorbing it. This helps to keep the surface cooler and reduces heat gain in the surrounding area.
Metamorphic rock
A rough surface would absorb and radiate heat more rapidly compared to a smooth surface. This is because a rough surface has more surface area in contact with the surrounding environment, allowing for more efficient transfer of heat through conduction and radiation.
