When the bread is cooked it turns to toast this change is not reversible describe a different non reversible change?
That is a chemical change. Physical changes can be undone. Burning a bit of paper is another non-reversible change.
Is egg cooking is a physical or chemical change?
This is a chemical change. Remember: An easy way to determine whether or not a change is chemical or physical is to ask if the process is reversible. Take the evaporation of water into account. When water evaporates, it can condense back into liquid water. It can be reversed because it is a physical change. Chemical changes are often permanent. Take the burning of wood, for example. This is a chemical change. Once you light wood on fire, it turns into gas. Only the trees and plants around you can take this gas and through photosynthesis, turn it back into wood. So it is a non-reversible process, and is a chemical process.
What is a ''non'' reversible reaction?
A reaction which cannot be reversed is called an Irreversible reaction.
Non chemical change from one state to another?
You will know that it's a non-chemical change because: 1. Non-chemical changes do not form a new substance. 2. They are generally reversible. 3. They are not accompanied by considerable heat change.
What are Four physical changes in a glass of milk?
Physical changes are those that do not alter the chemical composition of a substance. I hate to give out homework answers, but here's a push in the right direction: what in your kitchen could change a glass of water in a way that is reversible, and would not chemically alter it? Consider things like mixing with non-reactive substances and heating. There are many more that are probably within arm's reach.

What is a non reversible change?
A reversible change is a change you can make, then put back, however a non-reversible change is a change you can make, then it will be stuck like that
How is shredding a paper a non reversible physical change?
it changed from paper to paper.
Is tea a reversible change or non-reversible change?
It is not a reversible change. During boiling some components are extracted with hot water from the crushed dried leaves. It is impossible to restore the original leaves.
Is evaporation a reversible or non reversible change?
non --- Evaporation is reversible by condensation, lowering the temperature.
Is a burning candle a reversible or non reversible change?
Non reversible, after the wick has been burned, it is impossible to reverse the effects of the change.
Is making crisps from cooking oil and potatoes a reversible change or chemical reaction?
Most cooking processes are chemical reactions. Generally, the reactions are non reversible and once cooked, food cannot be returned to an uncooked state. So, frying potatoes causes a non reversible chemical reaction. The question is not as precise as it might be. Changes can be physical or chemical. They can also be reversible or non reversible but it is important to note that many chemical changes are reversible just as many physical changes are reversible.
Is physical reaction the same as physical change?
a physical reaction is non-reversible e.g. when you bake a cake or fry an egg. a physical reaction is reversible e.g. when you melt ice or chocolate. i did this in chemistry today, ^-^ (but did you mean a chemical reaction?)
Is a cooking eggs physical or chemical change?
This is a chemical change. Remember: An easy way to determine whether or not a change is chemical or physical is to ask if the process is reversible. Take the evaporation of water into account.

So it is a non-reversible process, and is a chemical process.
Is cutting of wood is reversible or irreversible change?
if you chop down a tree and cut it into a bunch of little peices... can you put that tree back together so that it can continue on living its boring tree life? the answer is no it is irreversible
What are physical change non examples?
Any idea is a non example of physical change.
