in both , the substance involved undergoes a physical change
The direct change from a solid to a gas is called sublimation.
sublimation!! :)
cvbnm,.
sublimation
vaporization
Vaporization.
The change from a liquid to a gas is called vaporization. Sublimation, evaporation, and boiling are all types of vaporization.
It is a known fact : Molar heat of sublimation = molar heat of fusion + molar heat of vaporization so, molar heat of vaporization = molar heat of sublimation - molar heat of fusion Mv = 62.3 kJ/mol - 15.3 kJ/mol Mv = 47 kJ/mol.
Vaporization is the process of a substance changing from a liquid to a gas, sublimation is the process of a substance changing directly from a solid to a gas, and condensation is the process of a gas changing to a liquid. Each process involves the transformation of matter between different states.
Vaporization is the process in which a liquid changes into a gas. There are two types of vaporization, evaporation and boiling. If a solid changes directly into a gas, the process is called sublimation.
These phenomenons are called melting, boiling, vaporization, sublimation, deposition, evaporation.
There are two names I think...One is "Deposition"and the other is "sublimation
