What else can I help you with?
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 melting a sample of gold an example of a physical or chemical change?
Melting a sample of gold is an example of a physical change.
Which process is an example of a chemical change?
Burning wood is an example of a chemical change. During combustion, the wood undergoes a chemical reaction, breaking down into new substances like ash, smoke, and gases. This change is irreversible and involves the rearrangement of atoms and the formation of new chemical bonds.
What an example of a physical change?
When it combines with Oxygen. Commonly called Rust.
Example of a physical rather than a chemicalchange?
Which of the following is an example of a physical rather then a chemical change? Which of the following is an example of a physical rather then a chemical change?
Fireworks exploding in the sky and giving off light are an example of a(n)?
chemical change
Fireworks exploding in the sky and giving off light is an example of?
The principle is based on chemical reactions.
Fireworks exploding in the sky and giving off light are an example of an what?
Fireworks exploding in the sky and giving off light are an example of a chemical reaction. The explosion of the fireworks is caused by the rapid release of energy stored in the chemicals, producing heat, light, and sound.
What are Fireworks exploding in the sky and giving off light are an example of?
Exothermic Change
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.
Are fireworks an example of physical or chemical change?
Chemical change. A good hint for this one is that there is fire involved, which usually means that the chemical itself is being changed. The constituent materials oxidize (burning quickly - explosion - is very rapid oxidization) and form new compounds i.e. the chemicals change.
Is the detonation of fireworks a physical or chemical change?
The actual detonation (a rapid oxidation reaction) is an example of a chemical change.The resulting blast of expanding gas, sound, and light; and the shredding of the casings are physical changes.
What an example sentence with exploding?
I can almost feel my head exploding with irritation when I come across a question without a verb.
Is fireworks an example of an endothermic reaction yes or no?
No. Fireworks involve exothermic reactions where chemical energy is converted into light and heat.
Example of physical and chemical?
A physical change is melting.A chemical change is combustion.
Which is an example of physical rather then chemical change?
Vaporization is a physical change, not chemical.
What is example of a physical rather then a chemical change?
Boiling is a physical change, not chemical.
