gas and liquid
Fuel that is not a liquid or solid can be a gas. Many road vehicles use natural gas or propane but I have not heard of an aircraft that does.Fuel that is not a liquid nor a solid is probably gaseous - like the natural gas we use for our cars.
Solid
Propane
The majority use liquid propane, and some are hooked into the home's natural gas line.Natural, Propane, Charcoal fuel.
Propane is a gas a room temperature if it is not compressed. However, if it put in a canister under high enough pressure, it will be a liquid even at room temperature. Propane is a liquid below -44 degrees F or if its compressed. Grill bottles are only fillid 80% full with liquid. so you can use the propane gas on the top of the bottle.
Liquefied petroleum gas is a gas at room temperature but is compressed into a liquid for transportation.
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
Propane burning is a chemical change. The propane reacts with oxygen. New compounds are the result of the process.Let me add a little more information to this. Propane stored in the tank is in liquid form under pressure (actually an equilibrium of propane gas in the top of the tank, and liquid propane in the bottom). When you open the valve, the gas escapes into the hose and goes to the burners.As the gas escapes, some of the liquid propane evaporates into gas form.The change from liquid to gas is a physical change.
Is a pencil a solid liquid or gas
LP, Liquid propane, Propane. All the same thing.
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.
