What else can I help you with?
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 chemical change as it is a machine.
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.
What is an example physical rather than a chemical change?
A car crash is physical.
Why does the sound of thunder indicate a physical change rather than a chemical change?
thunder
Is sunburn a chemical change?
No, sunburn is a physical change rather than a chemical change. It involves damage to the skin from overexposure to ultraviolet radiation from the sun, rather than a change in the chemical composition of the skin.
Why is a change in state a physical change rather than chemical change?
Because it can change from one state to another.
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.
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 chemical change as it is a machine.
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?
Sawdust is not a change. Making solid wood into sawdust by sawing it, would be a physical change.
Is moss on a branch a physical or chemical change?
Moss growing on a branch is a biological process rather than a physical or chemical change. However, if you're considering the changes that occur during moss growth, it can involve both physical changes, such as the alteration of the branch's appearance, and chemical changes, such as the decomposition of organic material and nutrient absorption. Overall, the presence of moss indicates ecological change rather than a straightforward physical or chemical transformation.
