5 Weird Physical Phenomena

Sublimation


It would appeal to logic that chemicals in the process of changing from the solid state to a gaseous state would have to pass through the liquid state before entering the gaseous state.

However, water is capable of transforming straight from a solid into a gas in certain situations. Sublimation may cause glaciers to disappear into thin air as lens-like concentration of sunlight turns the ice into steam.

Likewise, metallic elements such as Arsenic may actually transform directly into a gaseous state when heated, releasing toxic fumes. Water may sublime at temperatures below the melting point upon application of a heat source.
