A chemical change involves a change in a substance's chemical properties (characteristics that describe how it interacts with other substances).
A physical change involves a change in a substance's physical properties
(characteristics that describe certain features one can see with their 5 senses).

When bromine reacts with sodium to form a white solid is it a physical or chemical change?
The reaction between bromine and sodium to form a white solid is a chemical change. This is because the atoms are rearranging to form new compounds with different properties, indicating a chemical reaction has occurred.
Is ice melting at 0 degrees Celsius a chemical property?
No, the process of ice melting at 0 degrees Celsius is a physical change, not a chemical property. It involves a phase change from a solid to a liquid state without any change in the chemical composition of the ice.
Is scrubbing the floor a physical or chemical change?
Scrubbing the floor is a physical change because the appearance or state of the floor is altered without changing the chemical composition of the materials involved.
Is color change a physical or chemical change?
It depends. In most cases, it is a chemical change as the different colored species have different chemical structures. However, it is possible to change color by very finely dividing particles of matter and this is a physical change.
Is melting copper an example of chemical change?
It can be. Temperature increases usually induce physical changes in the broad sense. If the change in temperature merely induces a state change (for instance, the copper is melted - becoming a liquid) then it is purely a physical change. Presuming that heating will occur in the presence of air, it will also increase the rate of oxidation and, therefore, be indirectly inducing a chemical change.
Differences between chemical and physical change?
A chemical change results in a change in chemical composition, while a physical change does not.
What is the differences between physical and chemical change in tabular form?
physical change are reversable
What is the differences between a physical and chemical change in a candle?
The physical change will keep the atoms the same not moving but the chemical change will make it move around with energy.
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.
What is the difference between chemical change and physical 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.
Is the separation of cream and milk a chemical change?
No, the separation of cream and milk is a physical change, not a chemical change. It occurs due to differences in density between the two components and can be reversed by mixing them back together.
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.
What is the difference between a physical and chemical change?
A physical change is reversible, a chemical change is not.
What is the difference between chemical physical change?
a physical change is reversible but a chemical change is irreversible
What is the diffrenece between a physical change and a chemical change?
Physical change is a change in the structure. Chemical change is a change in the composition. Melting is a physical change. Complexing is a chemical change.
What are the differences between physical and chemical changes?
Physical changes involve a change in appearance or state of matter without altering the chemical composition, while chemical changes result in the formation of new substances with different chemical properties.
