Is ripping your jeans chemical or physical change?
Physical - there are no chemicals involved
What is always a characteristic of a chemical change but not always a characteristic of a physical change?
When a chemical change takes place, the chemical structure of particles involved changes (i.e. one or more new substances are formed). In a physical change, the physical state of the particles involved changes (e.g. a solid melts and becomes a liquid). The chemical structure of the particles does not change, and no new substance is formed.
How you tell if matter has undergone a chemical change or a physical change?
If a chemical change has occurred, the chemical composition has changed and new products will have formed, different from the reactants. If a physical change has occurred, the chemical composition does not change and no new products will have formed.
Is cutting your fingernails physical or chemical change?
Cutting your fingernails is a physical change because the composition of the material (keratin) remains the same before and after cutting. A chemical change involves a change in the chemical composition of a substance.
When a substance undergoes a phase change what occurs a particle change a chemical change a new substance is formed a physical change?
During a phase change, the substance transitions between different states of matter (solid, liquid, gas) without any change in the chemical composition of the particles involved. This means that there is no new substance formed and no chemical change taking place, it is solely a physical change.
What is a fact about chemical change and physical change?
chemical change is when during a chemical reaction a new substance will be formed while in physical change no new substances are formed
When substances are formed that are different from the starting substances has physical change occurred?
No, a physical change refers to a change in the form or appearance of a substance without any change in its chemical composition. If new substances are formed with different chemical properties, then a chemical change has occurred, not a physical change.
What is the different between a chemical and physical change?
In a chemical change a new substance is formed.
What is Heating up metal with a flame is that a physical or chemical change?
No, it is a chemical change. The metal oxide formed is a new substance.
What is made from a chemical reaction?
In a chemical reaction something new is created. A chemical change is inreversible where as a physical change is. In a physical change nothing new is formed.
Is ripping your jeans chemical or physical change?
Physical - there are no chemicals involved
Scientifically what is a physical change?
A change in which no chemical bonds are broken or formed.
Is a tree a chemical or physical change?
it's a physical change because no new substances were formed.
Why cutting of tree is a chemical change?
it is a physical change because its chemical composition does not change and no new substance is formed
What are the products formed after a mixture is formed?
The product formed depends with the type of change that occurs whether it is a chemical or a physical change.
Is burning fuel a chemical or physical change?
It's a chemical change because new substances are formed.
What is chemical reaction physical reaction?
A physical change is one in which the chemical composition of the substance does not change. A chemical change is one in which new products are formed with their own unique chemical compositions and properties.
