I'm assuming you are asking about a single substance existing in all three phases of matter. The conditions under which a single substance can exist at equilibrium in all three phases (solid, liquid, and vapor or gas) is called the triple point. The triple point for water occurs at exactly 273.16 K (0.01 °C) and a vapor pressure of 611.73 pascals (ca. 6.1173 millibars, 0.0060373 atm).
Sure, ice, liquid water, and water vapor can simultaneously exist in nature (for instance, in a lake which is half frozen), but those phases are not in equilibrium with each other. Either the ice is melting, the water is freezing, the vapor is condensing, etc.
liquid and gas because they both have an ability to flow
Solid
air is neither liquid or solid, it is a gas
liquidI would say that it is actually both a liquid and a solid. It definitely is NOT a gas. It "sticks" together like a solid, but still has the viscosity, or fluidity, of a liquid.
evaporation solid to liquid - melting liquid to gas - evaporation gas to liquid - condensation liquid to solid - freezing solid to gas and gas to solid - sublimation
A mist is a gas. It is not a solid or a liquid. An example of a solid would be a rock, of a liquid would be water and of gas would be steam. Other examples of are gas: steam vapor/vapour (water vapour)
Is a pencil a solid liquid or gas
Solid
There are three basic states of matter: solid, liquid, and gas. The number of combinations possible from these states is 3! (3 factorial), which equals 6. The six possible combinations are solid-liquid-gas, solid-gas-liquid, liquid-solid-gas, liquid-gas-solid, gas-solid-liquid, and gas-liquid-solid.
Solid in solid: metal alloys. Liquid in liquid: vinegar dissolving in water. Gas in gas: air. Solid in liquid: salt dissolving in water. Liquid in solid: mercury absorbed by gold. Gas in liquid: carbon dioxide dissolving in soda. Solid in gas: smoke particles in air. Liquid in gas: water vapor in air. Gas in solid: hydrogen absorbed by palladium.
a feather is a solid
