Yes
Physical cause it is still bread
Mold needs moisture to grow. Toasting removes the surface moisture. Toasted bread will mold. It just takes longer.
Yes, toasted bread likely weighs less than untoasted bread. This is because toasting removes some of the moisture content, making the bread lighter.
Once the slice of bread has been toasted (charred) it can't be turned back into the original untoasted state.
Bread is toasted, eggs and bacon fried. All 3 produce a chemical change. If you squeeze juice from an orange, it is a physical change. Bake muffin batter, it undergoes a chemical change to become muffins. Now I am hungry.......
It is a chemical change.
because it can no be reversible once it has been burnt it cannot be turned back into bread or slightly toasted toast, that is its permanent form :D
Physical cause it is still bread
physical change
Toasting bread is a chemical change because the heat causes the chemical composition of the bread to change, resulting in the browning or caramelization of the sugars in the bread. This change is irreversible, unlike physical changes such as cutting or crushing bread.
This would be a irreversible change. If you think about it, if you let the bread sit after being toasted it will not become un-toasted. It may become mushy after time but once you toast it its toast.
Toasted bread does not have fewer calories than untoasted bread. The calorie content of bread remains the same whether it is toasted or untoasted.
No. It's a chemical change because the process is irreversible, there is a change in colour and a change in odour.
The calories in toast should have the same calories as the bread that was toasted because the only difference is the water that evaporates when the bread is toasted. Water has not calories so there is no change in calorie content (until you butter it, then you've got calories).
Toasted bread does not spoil! it molds!
yes, it is now toasted bread or toast for short.
Toasted cheese and bread.
