Sublimation is the process of changing a solid substance into a gaseous substance without going through the liquid phase. In simple words, a solid substance directly evaporates and become a gas without being a liquid first.

Deposition is the opposite process of sublimation. It is also known as de-sublimation. Here, a substance in the gas phase changes into the solid phase without passing the intermediate liquid state.

Examples of Sublimation:

1.."Dry ice" or solid carbon dioxide sublimes.

2..Snow and ice can sublime in the winter months without melting.

example of deposition

Deposition is one of the phases of matter changing. It is the gas to solid phase.. Water vapor to ice and physical vapor to film are examples of deposition. Frost forming on a leaf is another example of deposition.

Answer:

Sublimation is a type of phase change that takes place when a solid turns directly into a gas, skipping the liquid phase. The contrary of sublimation is vapour deposition.

  • The term" sublimation" only applies to a physical change of state and not to the metamorphosis of a solid into a gas during a chemical response
  • One common illustration of sublimation is solid carbon dioxide, known as dry ice. At room temperature( 293 K) and pressure(1.01 Bar), dry ice sublimates into carbon dioxide vapour.
  • Sublimation is an endothermic process that happens below a substance's triple point in its phase diagram

A deposition is when a substance in gas form changes states to become a solid.

  • The gassy substance gets deposited( generally as chargers) bypassing the intermediate liquid state.
  • An illustration of the deposition is when water vapour in the atmosphere changes directly into ice, similar to the conformation of frost.
