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.
Why is burning a candle chemical change?
Phenomena during the candle burning:- melting- evaporation- oxydation- thermal decompositionIt is a chemical change because gas is use as a chemical. It also has friction when your trying to light it. The match is similar.Burning a candle is a chemical change because the wick is being changed into two things: ash and smoke. It is no longer a wick, and it's properties have changed.because oxygen is reacting with the flame...
What are non examples of physical change?
Any idea is a non example of physical change.
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.
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
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 evaporation a reversible or non reversible change?
non --- Evaporation is reversible by condensation, lowering the temperature.
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

What is a Non reversible physical change for water?
One example of a non-reversible physical change for water is freezing. When water freezes, it changes from a liquid to a solid state, and this change cannot be easily reversed simply by raising the temperature back to its original state.
Is candle burning a spontaneous or non spontaneous reaction?
Candle burning is a spontaneous reaction. It is an exothermic reaction that occurs naturally and releases heat and light energy as the wax is being oxidized in the presence of oxygen from the air.
What is the antonym of reversible?
irreversible, non-reversible, one-sided
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.
What are non examples of physical change?
Any idea is a non example of physical change.
How is shredding a paper a non reversible physical change?

How do you make a candle burn green?
To make a candle burn green, you can use green colored wax or add green dye when making the candle. Be cautious when adding dyes to wax as using too much can affect the burning properties of the candle. Additionally, using eco-friendly and non-toxic dyes is recommended for safety.
