What is the difference between a chemical and a physcial change?
chemical change is easily reversible whilst physical is not reversible
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 the difference between chemical change and physical change?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
Is slicing an apple is a chemical change or a physical change?
This is a physical change. You only change the shape and size of an apple by slicing it. Chemical changes would mean changing the molecular composition of the apple.
What is the difference between a physical and chemical change?
A physical change is reversible, a chemical change is not.
Is slicing a bread a chemical or a physical?
Slicing bread is a physical change, because each slice of bread has the same chemical composition as it had before it was sliced.
Is slicing a bread a physical change?

Is slicing bread chemical change?
No, slicing bread is a physical change. The act of cutting the bread into smaller pieces does not alter its chemical composition.
Slicing bread physical change?

Is slincing bread physical or chemical change?
Slicing bread is a physical change because it does not change the chemical composition of the bread.
Is slicing bread physical change?
It is a physical change
Is bread a physical change?
No. It's because it can not be reversible.
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 baking a bread a reversible change?

What are the 3 examples of physical change?
ripping paper slicing bread trimming nails
Is toasting of bread a physical or chemical change?
Physical ------------------- It is a chemical change because some compounds from bread are thermally decomposed. The reaction is not reversible.
Is slicing bread a physical change or chemical change?
This is a physical change: the bread is not being chemically altered, and would have the same nutritional value whether eaten from the loaf or the slices. It would, however, be difficult to exactly reverse this physical change because of the nature of the product.
