Is white phosphorous ignites easily a chemical or physical property?
chemical
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.
What ignites the gas in a neon light?
Electricity. Ignites probably isn't a good word to use, because the neon gas doesn't actually burn.
What happens to a glowing splint in the presence of oxygen?
it re-ignites
What element ignites spontaneously when exposed to air?
Phosphorus (15)
Which ignites more easily Gasoline or Diesel oil?
GasolineGasoline
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 physical change?

Would a loose manifold cause problems?
Absolutely, the manifold must seal to contain the compression the engine generates when the spark ignites the gasoline.
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
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 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.
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.
Is a match ignites to form ash and mixture of gases a physical or chemical changes?
Ignition of any kind is always a chemical change.
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.
