Toasting a slice of bread is physical change?
No it's a chemical change as you can't 'untoast' the bread.
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 melting a slice of cheese a chemical change?
It is changing from a solid to a liquid, which is a physical change.
Is the stomach physical or chemical change?
A physical change could be easily described as a change that you can reverse. Melting an ice cube, than freezing it, etc. Eating is actually both because you chew the food and swallow it. After that your stomach's enzymes dissolves the food and readies it for your digestive system. :D

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 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.
Does an ice cream melting in a bowl count as a chemical reaction?
No, its a physical change. It make be changing from a solid to a liquid, but it is not changing at a chemical level, only at a physical level. No matter how you slice it, it is still ice cream (but maybe a little drippy).
