                                                    Solid to Gas

The process which is used to convert solid to gas is known as sublimation. It diverts the flow of instinctual energy and solid converts into gas without passing through the liquid stage. Only some compounds like solid carbon dioxide can go through the process at normal atmospheric pressure. It changes from the solid state to gaseous state without being a liquid. Most of the objects require low atmospheric pressure to go through sublimation. Iodine can be converted into gas from solid directly without melting only under extreme temperatures.

Fast Facts: –

  • The process of sublimation is most commonly used to describe the process of snow and ice changing into water vapor.
  • It is not easy to see the process occurring, especially with the ice.
  • Sublimation is a type of phase transition as the substance is being changed from one state to another.
  • The reason of sublimation is that the substance absorbs energy so quickly that from its surroundings that it never melts.
  • Freezer burns are the result of sublimation of ice into water vapor.
  • Element arsenic will also sublimate from solid into the gaseous state.
  • It is the process which is the main reason behind wearing down of glaciers.
  • This process is also used for purifying compounds and especially for organic compounds.
  • Latent fingerprints on paper can be revealed with the help of sublimation of iodine.
  • Dry ice is used to create fog effects because it sublimates very quickly.
