In northern climates it is common to have a layer of frost form on cars that have been out overnight in the winter. During the day the frost disappears despite the temperature remaining below freezing. How? a) the frost melts due to the sun heating the surface of the car above the melting point B) the frost evaporates due to the sun heating the solid c) the frost cycles as does the saturation level of moisture in the winter air does from night to day The frost sublimes directly from solid ice to water vapor e) none of the above
