the changes which can be reversed by reversing the conditions are reversible changes.
the changes which cannot be reversed by reversing the conditions are irreversible changes.
A reversible answer is when you make a change to something to create another thing EG water to ice and ice to water. A irreversible change is when you change something and it can't be changed back.
A reversible change is when you can heat or melt a solid into a liquid or gas and when you cool it down it becomes a solid again. A irreversible change is when you heat or melt a solid into a liquid or gas and when you cool it down it stays the way it is and doesnt turn it back into a solid.
Reversible are changes that you can change back to where it started e.g. ice you can freeze it from liquid water so it is ice and then you can melt it back to water, and back again ... etc.
Irreversible changes are the ones you can not change backward to originals e.g. cake you cannot take the flour and all the stuff away and then put it all back together.
Anyway,
REVERSIBLE CHANGES are changes that are reversible ( if you want to define it more look 'reversible' up in the dictionary)
Eg:-
- Melting of ice & Evaporation of water (etc.)
- Melting of wax
- Melting of butter
- Mixing pebbles and sand.
IRREVERSIBLE CHANGES are changes that are not reversible
Eg:-
- Ripening of fruits
- Burning paper
- Burning of Magnesium (Mg) ribbon
- Curdling of milk
- Cooking of food
- Fermentation
- Digestion
it is an irreversable change as the original products can't be retained if there is a way to reverse it, i havent heard of it!
yes , all the physical changes are reversible changes.
physical changes are sometimes reversible
The difference between reversible and irreversible is that reversible changes can be changed and irreversible changes cannot. Apart from sometimes but it usually is really hard. Also when the change is reversible no new substances are formed. When the changes are irreversible they are. Something that is reversible can be changed, something that is irreversible cannot be changed. For example, bread into toast is an irreversible reaction, because you cannot turn the toast back into bread.

no
No, it is not.
chemical reactions are irreversible but physical changes are reversible
A reversible change is where like if you had some ice, you could melt and then change it back to ice again making it a reversible. An irreversible change is something that can't be reversed, like burning food, as you cannot unburn it. Hope I helped!

freezing is reversible because you can melt whatever it is you froze can't you
