Is a tree limb breaking a chemical or physical change?
It is a physical change: the wood (mostly cellulose) is not changed by the breaking. However, the living cells (if any) in the branch will begin to change chemically when exposed to the air and cut off from the xylem and phloem in the rest of the tree. Eventually the cells will die and the wood will rot (chemical changes).
Is sodium turning black when exposed to air a chemical change?
the answer is yes because sodium is a solid right right so being exposed by a chemical is changed.
How long does it take for blood to oxidize and change color when exposed to air?
When blood is exposed to air, it typically takes around 15-30 minutes for it to oxidize and change color, turning from bright red to a darker, brownish hue.
Is a silver tarnish a physical or chemical change?
It is a chemical change. Oxygen from the air combined chemically with the silver to form silver oxide- that is the tarnish.
Is a inflation of a car tire a chemical change?

What cause bannas to mold?
There exposed to air which causes the figments in the banna to change color due to the difference of air purity
Why do some fruits change colour when exposed to air?
When fruit flesh is exposed to air, it experiences oxidation, much like iron does. This reaction doesn't result in the rust that iron's reaction does, but it is responsible for the brown coloring that this exposed fruit flesh takes on.
Is a tire is inflated with air chemical or physical?
Inflating a tire with air is a physical change because it is not changing the tire chemically. It is only changing the physical appearance of the tire.
What will happens to a plant exposed to air?

Why does liquid nitrogen exposed to air is a physical change?
When liquid nitrogen is exposed to air, it rapidly evaporates and turns into nitrogen gas. This process is a physical change because only the physical state of the substance is changed from liquid to gas, without altering its chemical composition.
Does chlorine evaporate when exposed to air?
Yes, chlorine can evaporate when exposed to air.
What change happens when Fe 203 have when it hits humid air?
Fe2O3 is not going to oxidize further when exposed to humid air. At STP, it is a stable compound.
