Many gases solidify if cold enough. Famously, carbon dioxide (known as dry-ice when frozen) doesn't have liquid phase at atmospheric pressure.
Gas to liquid. Also, gas to solid.
2CaO is a solid. It is the chemical formula for calcium oxide, also known as quicklime, which is a white crystalline solid at room temperature.
It is possible for a gas to dissolve into a solid, in which case you could say that the mixture of solid and gas is a type of solution. An example is hydrogen dissolving in platinum.
Solid
It is aqueous. it can also be a solid or a gas but most commonly it is aqueous
Evaporation would be the phase change from liquid to gas. The phase change from solid to gas is called sublimation. A liquid can also boil and become a gas.
a feather is a solid
No, a solution is a homogeneous mixture composed of two or more substances. The solute is the substance that is dissolved in the solvent. The solute can be a solid, liquid, or gas, and the solvent is typically a liquid, but can also be a gas or solid.
Dry Ice, also known as Solid Carbon Dioxide
cchemical change and energy change also the change of a gas to a liquid
No, a solid is a solid and a gas is a gas. They are two separate states of matter.
Iodine. Also, the process is called sublimation (phase change from solid --> gas)
