Which is an example of a physical change A Gasoline ignites B Water evaporates C Wood rots D A nail rusts?
B Water evaporates is an example of a physical change. In this process, water changes from a liquid to a gas without altering its chemical composition. In contrast, gasoline igniting, wood rotting, and a nail rusting involve chemical reactions that change the substances' chemical structures.

Is white phosphorous ignites easily a chemical or physical property?

What is an example of flammable matirial?
An example of flammable material is gasoline, which ignites easily and burns rapidly when exposed to an open flame or spark. Other common flammable materials include paper, wood, and certain types of alcohol. These substances can catch fire quickly and pose significant fire hazards if not handled properly. Always store flammable materials in safe, designated areas away from heat sources.
What is the reaction called when a mixture of gasoline and air encounters a spark and explodes?
The reaction is called combustion, specifically combustion of the gasoline-air mixture. The spark ignites the mixture, leading to a rapid release of energy that causes an explosion. This is the principle behind how internal combustion engines work in vehicles.
Is the liquid propane in a barbeque ignites upon contact with a spark a chemical or physical change?
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.
How does candle wax compare with gasoline and methane as fuel?
Candle wax, gasoline, and methane are all fuels, but they differ significantly in their properties and combustion characteristics. Candle wax, primarily composed of hydrocarbons, burns slower and produces less energy per unit compared to gasoline, which is a more refined and energy-dense liquid fuel. Methane, a gas, ignites easily and burns cleanly, producing mainly carbon dioxide and water, whereas candle wax and gasoline can produce more soot and pollutants. Overall, while all three can be used as fuels, gasoline and methane are generally more efficient and cleaner-burning options compared to candle wax.
Which ignites more easily Gasoline or Diesel oil?
GasolineGasoline
What engine is an example of an internal combustion engine?
The four-stroke engine used in automobiles is an example of an internal combustion engine.
Gasoline can power a car because the fuel has what kind of energy?
Internal combustion reactions power the car. The gasoline ignites, and the spark creates the power for the car.
Is white phosphorous ignites easily a chemical or physical property?

Would a loose manifold cause problems?
Absolutely, the manifold must seal to contain the compression the engine generates when the spark ignites the gasoline.
What burns the fuel in cars?
The sparks plugs fire and ignite the fuel in a Gasoline engine, and compression compresses the fuel until it ignites in a Diesel engine.
If you mix co2 with petrol in an engine what happens when it ignites?
Mixing Carbon Dioxide (fills fire extinguishers) with Gasoline will prevent ignition. So nothing
Which cars run on electricity and gas?
All gasoline cars run on both - electricity is required to create the spark which ignites the fuel/air mixture.
Where was diesel found in the world?
Diesel oil is a fraction of petroleum. It ignites easier than gasoline, on just compression heating without needing a spark.
What energy transformations occur when a car engine burns gasoline?
a controlled explosion (combustion) of fuel and air ignites expnds and is converted to rotational torque (power)
How is a gasoline engine different from a diesel engine?
A gas engine ignites gasoline in the piston chamber with a spark from a spark plug. The expanding gas then pushes the piston out and the motor moves forward. A diesel engine uses diesel fuel, different from gasoline, and the fuel is compressed by the piston until it ignites, sending the piston out. There are no spark plugs in a a diesel engine. Some diesel engines will have "glow plugs" which are used to initially start the engine but once started, compressing the fuel is the method of ignition.
Why does gasoline ignite?
Gasoline ignites because gasoline is flammable. (simple answer) A more detailed answer would be. Gasoline produces flammable vapors at a much lower temperature than almost any other 'common' chemical. It is the vapors that ignite rather than the chemical itself. Also Gasoline vapors are heavier than air. Any 'Flammable' chemical will ignite in the presence of an open flame or spark if there are sufficient fumes.
