What changes can't be reversed by physical means?
Chemical Changes
Is melting ice a chemical or physical change explain?
It is a physical change because when you have a chemical change it changes the properties and makes it into a new thing, and it can't be reversed. Physical changes are usually just changes of states (solid, liquid, gas) and a physical change can be reversed.
Are chemical changes irreversible If yes then what about the chemical reactions that are reversible Don't we say that all chemical reactions are chemical changes?
some chemical changes can be reversed but they are hard to reverse usually
Are glass breaking and sugar dissolving examples of physical changes?
Yes, a physical change is not permanent and can be reversed.
What is the difference between chemical and physical changes?
A chemical change is when something cannot be reversed and often a precipitate (solid) is formed. While a physical change can be reversed e.g bending a piece of wire.

The answer is true.
Why do you think the sublimation of dry ice and expansion of gases are not chemical reactions?
Because they are changes of state - physical changes - VERY easily reversed.
How can chemical change be reserved?
Reversible changes are the chemical reactions that can be reversed, however most are non reversible. The ones that can be reversed is because the reaction can flow both ways.
