If you fry an egg it turns white and goes solid is it a chemical reaction? well no it isn't a chemical reaction cos it can not be reversed back to what it was in the first place. it can also be known as physical reaction xx
hope that helped xx happy to help xx
Yes, as long as the liquid changes to solid, it is considered a chemical change.
I am almost positive this would be a physical change. The yoke is still yoke, it has just changed forms. It's just like when water freezes, it is still water and is still H2O with not change in the chemical makeup.
FROM SophhXxX :REALLY? i didnt know that! are you sure this is true cos I really need it for my homework. thankyhuu x ;)This is an example of a physical reaction. The chemical makeup of the egg has not changed. It has merely changed forms, similar to watching water evaporate. The water is still H2O, just in a different form.
a chemical change. Because it involved the application of heat and it is not reversible.
Its a chemical change because it cannot be reversed :)
Chemical for sure
Yes, it is a chemical reaction.
physical change
It's a physical change.
Its physical because the chemical properities of it doesn't change.
The thermal decomposition of baking powder is a chemical change.
It depends on what is boiling. If you are boiling WATER, then it is NOT a chemical change, it is a physical change (change of state from liquid to gas). If you are cooking food on the stove, a chemical change is occuring. That is, the chemical bonds within the food molecules are actually changing. One way you can tell that it is a chemical change is that you can't "uncook" food, but you can condense steam back into water.
This is a physical change.
Cooking oatmeal is a chemical change.
yes, cooking is a physical change. Mostly stuff that are cooked are chemical changes
Cooking is a chemical transformation.
Physical
physical change
Cooking is a chemical process.
It's a physical change.
no,it is chemical change
Cooking is a chemical process.
Physical change :D
It is as irreversible change, so it is chemical.
