Ignition of matches a chemical or physical change?
The ignition of matches is a chemical change because it involves a chemical reaction between the materials in the match head and the sulfur on the strike strip to produce heat and light. This reaction cannot be reversed to return the match to its original state.
Is the ignition of matches a chemical change?
Lighting a match starts a chain reaction which boosts the materials of the match tip, the wood with oxygen. These process changes the substance chemical formula, thus chemical change happens.
Is opening a box of matches a physical or chemical change?
it is physical change as you are not adding new chemicals and your are only changing the shape and it is revers able because once you open it you can close it again so it is definitely physical.
Is fireworks a physical or chemical change?
Fireworks involve both physical and chemical changes. The lighting of the firework (ignition) is a chemical change that triggers a series of reactions which results in the colorful display seen (physical change) as different elements are heated and produce light.
Is flammable a physical change?
Flammability is not a physical change; it is a chemical property of a substance. It describes the ability of a material to ignite and burn in the presence of an ignition source. When a substance burns, it undergoes a chemical change, transforming into different substances such as gases and ash, which is distinct from a physical change that does not alter the chemical composition of the material.
Do matches store chemical energy?
Yes.
What kind of energy does matches have?
chemical energy

When a rocket is launched is it physical chemical or nuclear change?
When a rocket is launched, it undergoes both physical and chemical changes. The ignition of the rocket fuel is a chemical change, as it involves the breaking and forming of chemical bonds to release energy for propulsion. The physical changes include the motion of the rocket as it moves through the atmosphere and the transformation of potential energy into kinetic energy.
