What are the differences between physcial and chemical changes?
Physical changes involve a change in appearance, shape, or state without altering the chemical composition of the substance. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are usually irreversible.
What are the differences between the physical and chemical?
in changes. Physical changes can be reversed. E.g. if you were to melt a block of ice, and then freeze it again, it would to some degree be reversed. This is a physical change. However, if you were to burn a peace of toast, the change would be chemical. Once the toast is burnt you cant get it back.
What criteria are used to distinguish between a chemical and physical change?
One distinguishing feature between physical and chemical changes is that a physical change can be reverse or turn back to its original form, but chemical change cannot be return to its form because the material change.
What is the difference between a chamical and physical change?
A chemical change results in the formation of new substances with different chemical properties, while a physical change involves a change in appearance, state, or form of a substance without altering its chemical composition. Chemical changes are usually irreversible, while physical changes can often be reversed.
What is the differnce between physical and chemical change?
Physical changes are changes in appearance, state, or form of matter without altering its chemical composition. Chemical changes involve the formation of new substances with different chemical properties. Examples of physical changes include melting ice or tearing paper, while examples of chemical changes include rusting of iron or burning wood.
What is the differences between physical and chemical changes in relation to fire services?
Physical changes are melting and boiling in this case; fire is a combustion, a chemical change.
Differences between physical changes and chemical changes?
Physical changes are changes that affect the form of a chemical substance, such as changes in state or shape, without changing its chemical composition. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.

what is the difference between chemical change and physical changes?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
What Is the difference between physical changes and chemical change?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
Write 3 differences between chemical and physical change?
Okay now here goes in a physical change no chemical reaction takes place. in chemical change chemical reactions take place. A physical change is reversible but a chemical change is not.In a physical change no new substance is formed(A+B=B) in a chemical change new substances are formed(A+B=C)
What are the differences betwen physical and chemical changes in terms of what happenes to molecules?
During a chemical change the molecule is transformed; during a physical change the molecule is not transformed.
How can you tell the difference between physical and chemical properties?
You can tell the difference by knowing that a physical property changes shape and that a chemical property changes the substance.
What are the chemical and physical changes of photosynthesis?
There are no physical changes. there are only chemical changes.
What is the difference between a chemical change and physical change?
A physical change changes the physical properties of an element like color where chemical changes change the chemical properties of an element and usually can't be undone.
What are the similarities between chemical and physical changes?
Both chemical and physical changes involve a transformation of matter. In physical changes, the substance's chemical composition remains the same, while in chemical changes, new substances are formed as a result of a chemical reaction. Both types of changes involve the absorption or release of energy.
