WebbIt is similar to condensation, except the substance goes directly from vapor to solid. The formation of frost is a good example: If warm, humid air (such as your breath) blows over a cold surface (such as a piece of metal kept in the freezer), ice will condense onto the surface directly from the vapor. Snow forms in a similar way. WebbAs a pot of water is boiled on the stove, steam rises out of the pot.
