No it's a chemical change as you can't 'untoast' the bread.
slicing it
It is changing from a solid to a liquid, which is a physical change.

The chemical change that occurs when a slice of bread burns in a toaster is called combustion. During combustion, the carbohydrates in the bread combine with oxygen from the air to produce carbon dioxide, water vapor, and heat energy. This process releases energy in the form of heat and light.
The energy content of bread can vary depending on the type and size, but on average, a slice of bread contains around 70-80 kilojoules.
Slicing bread is a physical change, because each slice of bread has the same chemical composition as it had before it was sliced.
No - you'll just have crunchier toast.
1. take a slice of bread out of the packet. 2. Put it in the toaster. 3. Wait.
To achieve the perfect toasting of French bread in the oven, preheat the oven to 375F, slice the bread evenly, place it on a baking sheet, and bake for 5-7 minutes until golden brown. Keep an eye on it to prevent burning.
It can be used both as a verb and a noun. I am toasting bread by the fire. (verb) The toast can have marmalade spread on it .(noun).
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.

Since it is the heat from the bread that causes the butter to change form (melt), and be absorbed by the bread, this should be classified as a chemical reaction.
everyone has slice of bread well.....not every one but i do have slices of bread!:-)
in one slice of the bread there would be over 90Kj
No, iodine solution will not change color when tested on a slice of bread. Iodine solution reacts with starch, turning it blue-black. Bread does not contain starch in high enough amounts to produce a noticeable color change.
According to the United States Department of Agriculture, one slice of banana nut bread contains about 217 calories. This may vary depending where you bought the bread (i.e. grocery store, homemade, restaurant)
