Physical Property.
It is a physical process because the chemical composition remain unchanged.
physical
A chemical change occurs when a new species is formed, and is generally not reversible. A physical change can usually be reversed as in the case of instant coffee. The coffee goes from a solid to a solution. Evaporation of the water would give the coffee back as a solid.
Immiscible liquids are those that are incapable of being mixed or blended. Examples are lighter fluid and whiskey, as well as gasoline and grape juice.
A physical change changes the property of a substance without changing the substance completely. In other words, a physical change is reversible.This change that occurs in the physical property/properties of a substance without altering its composition. A physical change:Possibly canchange withstate of matter (sublimation, decomposition, evaporation, melting, freezing, and condensation).No new material is formed.Possibly can dissolve.Possibly can occur either by increasing or decreasing the temperature.Is reversible.A physical change is any change not involving a change in the substance's chemical identity.a physical change is the color shape taste and smell of a substance.A physical change is where an object changes is size/ shape
It is a physical process because the chemical composition remain unchanged.
physical
A characteristic property is a chemical or physical property that helps identify and classify substances. The characteristic properties of a substance are always the same whether the sample you are observing is large or small.
What is the chemical reaction of a dispoiable lighter
Helium(0.1786 g/L) is lighter than air(1.2 kg/m3) due to physical property density.Density of air is more than helium due to presence of many gase like oxygen carbon dioxide etc.
Density.

Hydrogen peroxide are mixed with dye and or lightener/bleach to make your hair lighter.
Its chemical make up
No. Lighter fluid is usually butane, a flammable substance known as a hydrocarbon with chemical formula C4H10. A spark ignites the butane, allowing the lighter to function.
The chemical make up of odorless charcoal lighter fluid includes methanol or ethanol.
what substance you get when you're done with the chemical change.ex: match+lighter=reactants. when you mix those a certain way, you get a light!
