How does a physical different from a chemical change?
A physical change doesn't change the molecule of a compound.
Are icicles forming on the edge of the roof of physical or chemical change?
No it is not. The chemical composition is H2O before and after freezing.
Is snow forming a physical or chemical property?
It is a physical change: water changes from gas to solid.
Is rust forming on a nail left outside a physical or chemical change?
because the chemical composition of the nail is changed, forming a new substance (the rust)
Is a physical change what happens when chemical bonds break and new bonds form?
No, a physical change does not involve breaking or forming chemical bonds. It only involves changes in physical properties like size, shape, or state of matter. Chemical changes involve the breaking and forming of chemical bonds to create new substances.
Is acidity physical change or chemical change?
An acid is a chemical compound, not a physical or chemical change.
Is a cavity forming a physical or chemical change?
chemical
What is a physical change and what makes a chemical change?
physical change may be change in colour,odour,state(solid liquid gas) of any compound but chemical behavior of that compound remains as such; while when compound's chemical composition is changed than it is called chemically changed...
Is water freezing and forming physical change or chemical change?
physical
Is it a chemical or physical change when oxygen is incorporated into hemoglobin to bring it to the cells?
This is a chemical change. When oxygen binds to hemoglobin, it forms a new compound with a different chemical composition. This process involves breaking and forming chemical bonds.
Is a scab forming over a wound a physical or chemical change?

Is ice berg a physical or chemical change?
An 'iceberg' is no kind of change, but the melting and forming is a physical change.
Is forming a bar of gold into wire a chemical change or a physical change?
Forming a bar of gold into wire is considered a physical change. This is because the gold's chemical composition remains the same during the process, only its physical shape is altered.
What kind of change occurs when a compound separates?
When a compound separates, it undergoes a physical change, not a chemical change. This means the chemical composition of the compound remains the same even though its physical state may have changed (e.g. from solid to liquid).
Is decomposing a chemical or physical change?
Decomposition of any compound e.g. when heated CaCO3 compound decomposes to CaO and CO2 compounds, gives different substances and hence a chemical change. Y.Ozkalay
