They have be heated to liquid form first, and from that they must be heated more to be able to evaporate into the air and become a gas.
Solids don't change their size or shape.
Liquids yes, gasses yes, solids no
Because there is a freezing point, a boiling point so Solids can change into liquids and liquids can change into gases and all over again!!!!!!!!!!!!!!
shape and volume
Solids are not completely incompressible, but they are much less compressible than liquids and gases. This means that solids can be compressed slightly under high pressure, but their volume does not change significantly compared to liquids and gases.
Gases have the property of indefinite shape and volume, as they expand to fill any container. They also have low density compared to liquids and solids. Gases can be compressed and expand easily when heated.
No, cooling solids typically causes them to contract and become denser, rather than changing into gases. Cooling a substance lowers the kinetic energy of its molecules, which reduces the distance between them and causes the solid to solidify further. However, if the solid sublimes (changes directly from solid to gas), then cooling could cause it to transition into a gas.
solids cannot be poured , they cannot also change shape unless you bend it , break a bit of it or melt it. liquids can be poured. gases can not be condensed down
The solubility of solids and liquids show virtually no changes with pressure. However, solubility increases with pressure in the solubility of gases in liquids.
some solids,liquids and gases are dangers some are not dangers
Solids have a definite volume and gases have a variable volume
i would say solids but it depends on how good youare with solids or gases. hope this helps :)
