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 non reversible?
It changes the chemical composition of the burned object making it kinda hard to reverse
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...
How is shredding a paper a non reversible physical change?
it changed from paper to paper.
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.
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.
Is tea a reversible change or 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 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.
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.
