Difference between chemical and physical change?
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
Properties seen when one substance changes to another are known as?
there are two types of change. the first one is the physical change. the form or appearance of the substance is change but the chemical properties of the substance is not changed. example, water evaporates into the air, that is a physical change because from liquid, water changes into gas but it then comes back to water as rain. the other one is chemical change wherein the chemical properties of the substance is changed. example is burning of wood. wood is burned and turned into charcoal. the chemical properties of wood is different from the chemical properties of charcoal and charcoal is another substance.
Is wood rotting a chemical change or physical change?
it is a chemical reaction because a new substance is formed when the wood rots
What is a change that alters the form or appearance of a substance but does not make it into other substance?
It is considered a physical change. A chemical change involves chemical reactions that change the substance into another substance. A physical change typically only modifies the form or phase.
When oxygen is liquefied is it a physical or chemical change?
Physical because it is still Oxygen. A chemical change results in a chemical equation and thus a new substance. No new substance = no chemical change. Liquefaction is a physical property.
What is the diffence between physical and chemical properties as well an physical and chemical changes?
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
What are physical and chemical?
physical changes do not change the chemical properties of a substance
Difference between chemical and physical change?
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
What happens to the chemical and physical properties of a substance formed in a chemical reaction?
The chemical properties of a substance change during a chemical reaction, meaning the substance undergoes a chemical change and forms new substances with different properties. The physical properties may also change, such as color, texture, or state of matter.
Do chemical changes affect the chemical structure of a substance?
Yes, chemical changes result in a change in the chemical structure of a substance. During a chemical change, new substances with different chemical compositions are formed through the rearrangement of atoms and bonds. This is in contrast to physical changes, where the chemical structure remains the same even though the physical properties may change.
A change that affects the physical properties but not the identity of a substance is?
chemical change
What does not change when a substance changes matter?
The chemical composition of the substance does not change when it changes its state of matter. The arrangement of atoms and molecules may vary, but the elements present in the substance remain the same.
In a physical change some of the physical properties of the substance may be altered and the chemical composition?
In a physical change, the chemical composition of the substance remains the same, but some physical properties like shape, size, or state may change. This means that the substance can be reversed back to its original state without undergoing a chemical reaction.
Is it a physical or chemical change when a substance changes form but it remains the same substance?
it would be physical change because physical change is when the substance stays the same
Can the chemical properties of a substance be observed without changing the substance?
physical properties
Compare and contrast chemical and physical properties?
Physical properties are characteristics of a pure substance that can be observed without changing it into another substance. Chemical properties are characteristics of a pure substance that describes its ability to change into different substance.
Does a change in substances and properties go with physical change?
no, if it's a substance change then it's a chemical change. If it were a physical change then it would be the same substance
