The change in state from a solid directly to a gas is called sublimation. An example is frozen carbon dioxide which changes directly into gaseous carbon dioxide without going through a liquid phase.
The change of state (substance) from liquid to gas can be called many different things. A couple of names for it is evaporation and vaporization.
The change of a substance from a solid directly to a gas is called sublimation. As an example, frozen carbon dioxide sublimes into gaseous carbon dioxide without going through a liquid phase.
The change from a liquid to a gas is called vaporization. Sublimation, evaporation, and boiling are all types of vaporization.
Condensation.
Boiling or evaporation.
evaporation
Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid. Vaporization: the substance changes from a liquid to a gas. Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.
The process in which solid directly changes into gas is called sublimation. Solid carbon dioxide is a substance that changes directly into gas without melting. Sublimation happens because these substances have higher vapor pressure than melting point.
The change between solid, liquid and gas is known as a change of state and is affected by the substance and its temperature. E.g. at room temperature water is liquid but a 0oc it becomes ice, a solid.
When a substance changes from a solid to a liquid and vice versa, its density changes.
When heat is added or subtracted, it chemically changes the substance into a different type of matter.
Iodine
When a substance changes from a solid to a gas, called sublimation, it quickly becomes less dense.
Iodine for example.
Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid. Vaporization: the substance changes from a liquid to a gas. Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.
from a solid to gas
boiling point
It is called sublimation.
A phase change directly from a gas to a solid is called deposition.
The kinds of changes in substances that are always physical changes are changes in the state. This is the change from solid, to liquid and then to gas and the reverse.
-Solid and a liquid? -A liquid and a gas? -A solid and gas? from roop
A substance which changes state directly from a solid to a gas is said to have sublimed.
This change of phase is called sublimation.
