A solid without a defined crystal structure is amorphous.
A solid has a form, the gas is without form.
ICE is the solid state of water.
Sublimation
when solid turns in gas without passing in liquid,or gas turns in solid without passing in liquid form,the process is called sublimation. Sublimation
No, water in a solid form is most commonly referred to as ice. Physical conditions such as temperature and pressure are required for water to transition into a solid state.
This phenomenon is called deposition.
Dry ice is the solid form (state of matter) of carbon dioxide (CO2).Under normal circumstances, it will change state from a solid directly to a gas. It does this without melting (changing state to a liquid). We call the direct transformation of a solid to a gas sublimation, and dry ice is said to sublime when going directly from its solid state to a gas.
You may have your terms backward. Sublimation is the disappearance of the solid phase material in favor of the vapor phase material. No solid substance is formed during sublimation.
A solid that turns directly into a gas is dry ice. Sublimation
I would call it "no change".
Sublimation is the unique property in which a substance can go from a solid to a gas without becoming a liquid. Sublimation is a phase transition.
