Coal is a solid becuase we can see coal and we can feel it its hard and black.
Some fossil fuels are liquid (oil) some are solid (coal) and some are gas (natural gas)
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
Freezing (Liquid 2 solid) Melting (solid 2 liquid) Boiling (liquid 2 gas) Evaporation (liquid 2 gas) Condensation (gas 2 liquid) Sublimation (solid 2 gas) hope this helped
The general classes of colloids are sols (solid particles dispersed in a liquid), gels (cross-linked networks of solid particles dispersed in a liquid), and emulsions (liquid droplets dispersed in another liquid).
'boiling' or 'vaporization'
Coal is a solid, Natural gas is a gas and Oil is a liquid.
The three types of fossil fuels are coal, oil, and natural gas. Coal is typically solid at room temperature, oil is liquid, and natural gas is a gaseous state.

Solid

Coal is a solid, Natural gas is a gas and Oil is a liquid.
Coal (solid), petroleum (liquid), natural gas (gas).
Fossil fuels an example of three states of matter because they come in different forms: solid, liquid, and gas Coal is a solid. Petroleum is a liquid. Natural gas is a gas.
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
Is a pencil a solid liquid or gas
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.
