What is the unusual feature of solid to gas and gas to solid phase changes?

The three phases of matter (as classically defined) are solid, liquid and gas. Most phase changes that begin with solid and end with gas pass through the liquid phase on the way. Likewise, phase changes that begin with gas and end with solid pass through liquid on the way. Think of water... usually, from solid ice it passes first to liquid water, and only then does it evaporate to gaseous water vapor.
It is sometimes possible for solid to change directly to gas. or gas change directly to solid, but these phase changes are the exception, so they can be called "unusual".

What are the phase changes of matter?
The melting phase changes are Solid~Liquid~Gas and the freezing phase changes are Gas~Liquid~Solid
What phase changes require the addition of energy?
Phase changes requiring the addition of heat energy are the phase changes from solid to liquid, liquid to gas, and solid to gas. These phase changes are termed melting (solid to liquid), evaporation (liquid to gas), and sublimation (solid to gas).
What are the change of matter?
The melting phase changes are Solid~Liquid~Gas and the freezing phase changes are Gas~Liquid~Solid
What changes directly from a solid phase to a gas phase?
sublimation
What is the phase change in which a substance changes directly from a gas to a solid?
A phase change directly from a gas to a solid is called deposition.
What does a liquid become when you cool it and it changes phase?
When you cool a liquid and it changes phase, it becomes a solid.
What is unusual aout bromine?
My chemistry is a litte rusty but I believe that Bromine is unusual because it sublimates - goes from solid phase to gaseous phase without going through liquid phase.
What is the phase in which a substance changes from a gas directly to a solid?
A phase change directly from a gas to a solid is called deposition.
What are the phase changes of water?
solid,liquid and gas
What do you call the phase when solid changes to liquid?
frozen
What are the changes of phase in matter?
Solid, liquid, or gas.
What is a phase change in which a substance changes directly from a solid to gas?
A phase change directly from a gas to a solid is called deposition.
