Solids:
* Metal: The car's body, engine parts, chassis, wheels, etc. are made from various metals like steel, aluminum, and alloys.
* Plastic: Interior components, dashboard, seats, some exterior parts, and even engine parts can be made from plastic.
* Rubber: Tires, hoses, seals, and some interior components.
* Glass: Windshield, windows, headlights, taillights.
* Fabric: Seat upholstery, carpeting, headliners.
* Wood: (Less common) Some older cars or luxury cars might have wooden trim.
Liquids:
* Gasoline: The fuel that powers the engine.
* Engine Oil: Lubricates moving engine parts.
* Coolant: A mixture of water and antifreeze that helps regulate engine temperature.
* Brake Fluid: Hydraulic fluid that transmits pressure to the brakes.
* Power Steering Fluid: Helps make steering easier.
* Windshield Washer Fluid: Used to clean the windshield.
* Battery Acid: Electrolyte in the car battery.
Gases:
* Air: The atmosphere inside the car, as well as the air used in the engine's combustion process.
* Exhaust Gases: The byproducts of combustion, including carbon dioxide, carbon monoxide, and nitrogen oxides.
* Refrigerant: A gas used in the air conditioning system to cool the cabin.
* Nitrogen: Some tires are filled with nitrogen instead of regular air, as it can help maintain tire pressure better.
Note: Some components, like the battery, contain both a solid and a liquid (the electrolyte). The fuel, oil, and coolant can be considered both liquids and mixtures.
