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.
The two types of rocket fuel are liquid fuel and solid fuel. Liquid fuel rockets use a combination of liquid propellants, such as liquid oxygen and liquid hydrogen, that are mixed and burned to create thrust. Solid fuel rockets have a solid mixture of fuel and oxidizer that is ignited to produce thrust.
Fuel is typically stored in rockets either as liquid fuel in fuel tanks or as solid fuel in a casing. Liquid fuel rockets have separate tanks for liquid oxygen and liquid hydrogen or kerosene, while solid fuel rockets have a solid propellant mixture in a casing. Both types of fuel storage systems are designed to be safe, efficient, and controlled during flight.
The three forms of fuel needed for a fire to start are fuel in the form of a solid (such as wood or paper), fuel in the form of a liquid (such as petrol or oil), and fuel in the form of a gas (such as natural gas or propane).
Gasoline can be a liquid and a gas, I am not sure about a solid though.
Some fossil fuels are liquid (oil) some are solid (coal) and some are gas (natural gas)
liquid fuel
The three types of rocket fuels are liquid rocket fuel, solid rocket fuel, and hybrid rocket fuel. Liquid rocket fuel consists of liquid components that are combined and ignited to produce thrust. Solid rocket fuel is a mixture of solid components that burns to produce thrust. Hybrid rocket fuel combines elements of both liquid and solid rocket fuels.
There are solid rocket fuels, and there are liquid rocket fuels.
The two main types of rockets are liquid fuel rockets, which use liquid propellants like liquid oxygen and kerosene, and solid fuel rockets, which use a solid mixture of fuel and oxidizer. Liquid fuel rockets offer more control and efficiency, while solid fuel rockets are simpler in design and more reliable.
Rockets are propelled into space using liquid or solid propellants. Liquid propellants typically consist of liquid oxygen or hydrogen as the oxidizer and a fuel such as liquid hydrogen or kerosene. Solid propellants are a mixture of fuel and oxidizer that are combined into a solid form.
There are many examples, depending upon the use. Most often, liquid fuel is described as an option as compared to solid fuel. Rockets are one example where both solid and liquid fuels may be used. Liquid hydrogen is the common rocket liquid fuel. Cooking stoves can use solid or liquid fuel, in addition to gas. The most common cooking stove liquid fuel is alcohol.

Rockets commonly run on liquid fuel, solid fuel, or a combination of both. Liquid fuel rockets use liquid oxygen and liquid hydrogen, while solid fuel rockets use a solid propellant mixture. Both types of rockets generate thrust through a controlled combustion process.
Coal is a solid, Natural gas is a gas and Oil is a liquid.
diesel is a liquid fuel at the gas pumps.
Solid fuel rockets use a solid propellant mixture, which is more stable and easier to store compared to liquid fuel rockets that use liquid propellants. Iron rockets typically refer to solid fuel rockets using iron particles as part of the propellant mixture to enhance thrust. Overall, solid fuel rockets are simpler and more reliable but lack the efficiency and flexibility of liquid fuel rockets.
