What are some non examples of combustion?
Melting an ice cube is not an example of combustion, as it does not involve a chemical reaction with oxygen to produce heat and light. Dissolving sugar in water is another non-example, as it is a physical change and does not involve the chemical process of combustion. Boiling water is also not combustion, as it is a phase change from liquid to gas due to heat, not a reaction with oxygen.
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 the combustion of wood an example of a physical change?
Combustion (burning) is a chemical change.
What characteristic do photosynthesis and combustion share?
Photosynthesis and combustion both involve the conversion of chemical energy into another form of energy. However, in photosynthesis, light energy is converted into chemical energy, while in combustion, chemical energy is converted into heat and light energy through a chemical reaction.
Is combustion a physical change or a chemical change?
Combustion is basically a chemical reacting with oxygen to become the oxide and water is produced. So when alcohol combusts, for example, it is changed (burned) to carbon dioxide and water. In other words, there is a chemical change.
Is combustion a physical change?
NO its a chemical change for it can't be reversed
Is combustion a chemcial change?
Combustion clearly is a chemical change. In the combustion of a hydrocarbon, for example, you begin with the hydrocarbon and after combustion you end up with carbon dioxide (CO2) and water (H2O). This demonstrates that a chemical change has taken place.
Example of physical and chemical?
A physical change is melting.A chemical change is combustion.
Is lightning a burner a physical or chemical change?
It is a chemical change; burning (combustion) is a chemical process.
Is a tree burning a chemical or physical change?
Combustion is a chemical change, so the burning of a tree will be a chemical change.
Is combustion of gasoline a chemical change?
Yes, it is.
What chemical change can happen in the home?
Cooking involve a chemical change.
