Is the chemical formula H2o physical or chemical change?
The chemical formula H2O represents water. It is a chemical formula that describes the composition of a substance, in this case, water. Therefore, it is related to a chemical change rather than a physical change.
Is a computer a chemical or physical change?
A computer is a physical change, as it involves rearranging and assembling electronic components, rather than changing the chemical composition of the materials used to make it.
Why Milk souring is a physical change?
When milk sours, it undergoes a chemical change rather than a physical change. The bacteria in the milk ferment the lactose sugar into lactic acid, changing the chemical composition of the milk. This process cannot be reversed by physical means, distinguishing it as a chemical change.
Is beer going flat a chemical change?
Yes, beer going flat is a physical change rather than a chemical change. When beer loses its carbonation, the molecules within the beer are simply rearranging themselves, rather than undergoing a chemical reaction that changes their composition.
Is painting a door a chemical change?
No, painting a door is a physical change, not a chemical change. The paint is simply adhering to the surface of the door through physical means such as drying and curing, rather than undergoing a chemical reaction to form new substances.

Example of a physical rather than a chemical change?
when a rock is erodded by wind or waves is a physical change where acid rain eroding a stone figure would be chemical
Is a computer a chemical or physical change?
A computer is a physical change, as it involves rearranging and assembling electronic components, rather than changing the chemical composition of the materials used to make it.
Is fermentation sugar in bread physical change or chemical change?
It's a chemical change. Fermentation involves the production of alcohol and carbon dioxide from sugar. Since new substances are formed, the change is chemical, rather than physical.
Is a elasticity a physical change or a chemical change?
Elasticity is a physical property related to the ability of a material to deform and return to its original shape when a force is applied. It is not a change in the chemical composition of the material, so it is a physical property rather than a chemical change.
Why Milk souring is a physical change?
When milk sours, it undergoes a chemical change rather than a physical change. The bacteria in the milk ferment the lactose sugar into lactic acid, changing the chemical composition of the milk. This process cannot be reversed by physical means, distinguishing it as a chemical change.
What is an example of a physical rather than a chemical change an antacid sawdust or a cigarette?
