ans2. Yes it can. This is called sublimation. CO2 will change from solid to a gas without passing through a liquid stage. (At normal pressure and temperature at least.) Water ice may also do so at low temperatures - as in your fridge.
It can change from a gas to a solid to a liquid, or from a liquid to a solid to a gas. This change does not affect the composition of the matter.
solid
This change in the state of matter (liquid to solid) is called freezing; it is a physical change, the chemical nature of the molecules is not changed.
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
is when the solid is hard then the word is Melting to change to liquid
A solid is changed to liquid form of matter through melting A liquid changed to a solid is freezing
Submilation is when you change something directly from a gas to a liquid, with out changing it into a liquid first.
It can change from a gas to a solid to a liquid, or from a liquid to a solid to a gas. This change does not affect the composition of the matter.
Condensation (gas to liquid or solid or liquid to solid), vaporization (liquid or solid to gas), sublimation (solid to gas), solidification (liquid to solid), or melting (solid to liquid).
A solid, or even a gas. And back again (improved)liquid is a state of matter, which can be a solid, liquid, or gas. therefore, liquid can be changed into a solid or a gas. to do so, just change the temperature of the matter. :-D

Sublimation
the matter can change into liquid, solid and gas.
This change in the state of matter (liquid to solid) is called freezing; it is a physical change, the chemical nature of the molecules is not changed.
