Sublimation
From solid to liquid, from liquid to gaseous, from gaseous to liquid, from liquid to solid, and in sublimation from solid to gaseous or the reverse, chemical properties do not change.
The change in state would be known as melting. Just for your information: Solid to Liquid = Melting Liquid to Gaseous = Boiling Solid to Gaseous = Sublimation Gaseous to Liquid = Condensation Liquid to Solid = Freezing Gaseous to Solid = Deposition
thermol
A phase change occurs when a material goes from a gaseous state to a liquid state, a liquid state to a solid state, or the above in reverse order.
The change in state would be known as melting. Just for your information: Solid to Liquid = Melting Liquid to Gaseous = Boiling Solid to Gaseous = Sublimation Gaseous to Liquid = Condensation Liquid to Solid = Freezing Gaseous to Solid = Deposition
Yes there must be achange;but heat is required to change liquid state into gaseous state.
The change from a liquid to a gaseous state is called evaporation. During evaporation, molecules gain enough energy to escape from the liquid phase and become gas molecules. This process occurs at the surface of the liquid.
Condensation is the change of the physical state of matter from gaseous phase into liquid phase and is the reverse of evaporation.
In evaporation, a liquid such as water changes to a gaseous state. In sublimation, a solid such as ice changes driectly to a gas or vapor without going through a liquid state.
The process by which molecules at the surface of a liquid absorb enough energy to change to the gaseous state is called evaporation. This occurs when the kinetic energy of the molecules overcomes the intermolecular forces holding them in the liquid state.
