What type of change occurs when a car engine consumes gasoline - chemical or physical?
I don't think burning a gas to power a car is either Chemical nor Physical. If you burn gasoline to power a car, it is therefore a chemical AND physical change because both the chemicals and the look changes. However, a car being powered has nothing to do with the substance of gas being changed. If the car uses the gas to power itself, it'll turn the gas into gas again, so I'm not sure how this works. In conclusion, it's probably neither.
Is spilled gasoline drying a chemical or physical change?
Gasoline evaporation is a physical process.
Gasoline is a clear pink solution is it physical or a chemical property?
The color of gasoline, whether clear or pink, is a physical property. Physical properties are characteristics that can be observed or measured without changing the substance's chemical composition. In the case of gasoline, its color can vary due to the presence of additives or impurities, but this does not alter the fundamental chemical structure of the substance.
How is starting a car a chemical reaction?
Starting a car involves a chemical reaction between the fuel (gasoline) and oxygen in the air. The spark plug ignites the fuel-air mixture in the engine cylinder, leading to a combustion reaction that releases energy in the form of heat, which powers the engine. This chemical reaction generates the energy needed to start the car and keep it running.
Is a metal surface being ground a chemical change?
A metal Surface being ground is a physical change, not a chemical change.
Is carbon dioxide being produced by the combustion of gasoline in an automobile engine a physical or chemical change?
When the gasoline burns, it forms water and various gasses, so it is a chemical change.
If gasoline poured into a tank an chemical change?
Gasoline being poured into a tank is not a chemical change.
Is gasoline being burned a chemical change?
yes

Is less gasoline that remains in the gas tank as carbon dioxide physical change or chemical change?
The conversion of gasoline to carbon dioxide when it is burned is a chemical change, as it involves the breaking and forming of chemical bonds. This process releases energy in the form of heat and light.
Is spilled gasoline drying a chemical or physical change?
Gasoline evaporation is a physical process.
Is gasoline being evaporated a chemical change?
It's both a chemical change and a physical change. Gasoline doesn't explode. In order for there to be an explosion, the combustion must happen in a sealed container. The gasoline combusts with oxygen in the atmosphere to form carbon dioxide, water vapor, nitrous oxides, and soot, along with a lot of heat. The liquid gasoline produces mostly vaporous products, and in a sealed container, will generate very high pressures. The high pressure will cause the container to explode.
What energy takes place when a car's engine burns gasoline?
It goes from potential(before being burnt) to chemical(being burnt), to mechanical, with the pressure pushing the piston down.
What are examples of chemical energy being transformed into mechanical energy?
The (auto) engine found in many cars. Fuel is burnt (chemical change resulting in heat) and converted to mechanical energy (through the action of the pistons and crankshaft). Explode or burn the chemicals, e.g gasoline engine burns gas (petrol) and turns the energy into mechanical energy.
