What else can I help you with?
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.
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.
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 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 example of chemical changes?
non example of chemical change: one non example is ice. ice is NOT an example of chemical change.
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.
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
Is evaporation a reversible or non reversible change?
non --- Evaporation is reversible by condensation, lowering the temperature.
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.
How is shredding a paper a non reversible physical change?
Shredding paper involves cutting it into smaller pieces, which alters its physical form without changing its chemical composition. Once paper is shredded, it cannot be reconstructed back into its original form, making it a non-reversible physical change.
Is physical reaction the same as physical change?
No, physical reaction and physical change are not the same. A physical change involves a change in the physical state or appearance of a substance without altering its chemical composition, such as melting or freezing. A physical reaction, on the other hand, refers to a process where no new substances are formed, such as dissolving salt in water.
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.
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 a burning candle a reversible or non reversible change?
Burning a candle is a non-reversible change because once the wax is melted and the wick is burnt, it cannot be undone to return the candle to its original state. The chemical composition of the wax and wick is changed permanently.
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.
Are physical and chemical changes simply reversible and non reversible changes?
Chemical changes create new substances and cannot be reversed.Burning paperLighting a matchMixing sugar and waterPhysical changes do not create new substances and can be reversed.Crushing a canTearing paperChopping wood
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
