Sublimation and evaporation bring material into vapor phase, then what is the difference between two ?
Sublimation: The transition of a substance from the solid phase
directly to the vapor phase, or vice versa, without passing through an
intermediate liquid phase.
Evaporation: The conversion of a liquid (water) into a vapor (a
gaseous state) usually through the application of heat energy during
the hydrologic cycle; the opposite of condensation.

Thank you for clarifying that sublimation is going from a solid state to a vapor phase and evaporation is liquid to vapor. I'm trying to think of substances that can go straight from a solid to a vapor, but none come to mind. Can I have an example?
Iodine crystals and ammonium crystals

Cyclododecane is a substance used in conservation of organic and inorganic materials to stabilize surfaces and loose fragments for transport. When heated it turns into waxy substance that can be applied to friable surfaces to provide structure and strength, but over time it will sublimate, leaving the object in the same state and orientation that it was extracted in the field. Really cool stuff!
Can u pls give some more differences?
Ice to water vapor...very common in winter. Ice simply disappears without actually melting.
