Toasting a slice of bread is physical change?
Toasting a slice of bread is actually a chemical change, as the heat causes a chemical reaction in the bread that results in browning and changing its texture. This irreversible process is different from a physical change, which does not alter the chemical composition of the substance.
How is a slice apple a physical change?

Is melting a slice of cheese a chemical change?
It is changing from a solid to a liquid, which is a physical change.
A physical change to a slice of tomato is letting it rot?
Letting a slice of tomato rot is primarily a chemical change rather than a physical change. During the rotting process, the organic compounds in the tomato undergo decomposition due to microbial activity, resulting in new substances and changes in texture, color, and smell. While the physical appearance of the tomato changes, the underlying chemical composition is altered, making it a chemical transformation.
Is a pellet of sodium is sliced in two a physical change or a chemical change?
Physical, because each slice of pellet is still the same chemically: you have merely divided your one sodium block into two blocks of sodium. If it were chemical, some kind of notable chemical difference would have occurred (you would no longer have sodium, but something else).

Is leaving a potato slice and turns brown is a chemical or physical change?
It is a chemical change - oxidisation.
What liquids keep apples from browning?
Since you known that oxidation is responsible apple turning brown, you probably figured out that stopping oxidation would also stop the browning of apples. One way to prevent oxidation is to stop oxygen from reaching the PPO molecules in the cells. You block the oxygen by adding ascorbic acid (also known as vitamin C) to the apples to prevent the chemical reaction from taking place. Orange juice contains a lot of ascorbic acid. Placing an apple slice in contact with a orange slice or coating an apple slice in orange juice introduces ascorbic acid into the apple cells. Also, the orange juice and slice act as barriers to air, preventing oxygen from reaching the PPo molecules.
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.

What is an apple bee?
An apple bee is a community gathering to peel and slice apples for drying.
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.
