it is chemical because it can not be reversed
phisiological change,its not a physical or chemical change
Melting dry ice is a physical change because it is a change in state from solid to gas without altering the chemical composition of the substance.
A specific type of physical change is a change in phase. This involves the transition of matter from one state (solid, liquid, gas) to another without a change in chemical composition or bonding.

A physical state is physical and not chemical Physical Property is observed without changing a substance into another substance. Chemical property is the ability of a substance to change into different substance.

Chemical Change
Matter can undergo go both physical and chemical change.
Boiling is a physical change, not a chemical change. It does not alter the chemical composition of the substance. It is simply a phase change from liquid to gas.
Cutting bread is a mechanical or physical change, not a chemical change.
Melting dry ice is a physical change because it is a change in state from solid to gas without altering the chemical composition of the substance.
1. Any chemical reactions - a physical phenomenon.2. Mixing when chemical reactions are implicated - chemical change (depending on the type of the liquid and powder).
A specific type of physical change is a change in phase. This involves the transition of matter from one state (solid, liquid, gas) to another without a change in chemical composition or bonding.
A change in matter that changes its physical form is called a physical change. This type of change does not alter the chemical composition of the substance, but only its physical properties such as shape, size, or state (solid, liquid, gas).
