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.
What chemical change happens when you lite a firework with wax paper?
When you light a firework with wax paper, the heat from the flame causes the wax to melt and burn. This chemical change releases energy in the form of heat and light, igniting the firework composition inside the firework casing. The combustion reactions in the firework composition generate gases and produce the colorful light and loud sounds associated with fireworks.
When the fuse ignites the contents of a firework oxygen is consumed as a result of which type of change?
The oxygen consumption in a firework is a chemical change, as it involves the rearrangement of atoms and the formation of new molecules. This process releases energy in the form of heat and light, resulting in the colorful display we see in a firework explosion.
Is emission of light a chemical or physical change?
Most of the time the emission of light is a physical change but there are some chemical reactions which emit light as a byproduct of the reaction.
Does a firework give its own light?
Yes, a firework produces its own light through a chemical reaction inside the firework's shell. The explosion of the firework ignites various compounds that create colorful light displays in the sky.

When firework explodes is physical change or chemical change?
When a firework explodes, it is a chemical change because new substances are formed during the reaction. The compounds inside the firework undergo a rapid chemical reaction when ignited, resulting in the release of light, heat, gas, and sound, which are all evidence of a chemical reaction taking place.
Is fireworks a physical change?
Yes, fireworks involve a chemical reaction where the materials inside the firework combine to produce light, heat, and sound. This chemical reaction is not reversible, so it is considered a chemical change rather than a physical change.
Is a light bulb on a chemical or physical change?

Is flash cameras flashing a chemical or physical change?
The flash of a camera is a physical change, not a chemical change. A physical change is a change in the form of a substance without changing its chemical composition. In the case of a camera flash, electrical energy is converted into light energy, which is a physical process that does not alter the chemical makeup of the components involved.
