Why does the sun melt ice on sidewalks even when the temperature is below freezing?
All objects exchange energy with their environment. They do this via conduction, advection, convection and radiation. If water is involved, a change in the water phase (liquid, solid or gas) also will involve an exchange of energy.
Conduction moves energy by physical contact. Convection results from hot air rising. Advection by the wind moves heat horizontally. Continue reading
