no its not true
Cutting bread is a mechanical or physical change, not a chemical change.
I don't think so, mechanical change is when you use something to change the appearance of the object (your Jaw and food for example). Physical change can be caused bye a chemical substance and by and object ( mechanical change ) You welcome :)
Ripping pants is a physical change because the structure and composition of the fabric do not change at a molecular level. It is a mechanical alteration that does not involve a change in the chemical makeup of the material.
It is a physical change, as the chemical integrity remains the same.
it is a chemical change
Physical... chemically, it's still the same substance,
Roasting a marshmallow is a physical change, not a chemical change. The marshmallow undergoes a change in its physical state as it is heated, but its chemical composition remains the same.
it would be physical change because physical change is when the substance stays the same
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
physical change since the egg and the contents inside do not become a new substance they remain the same only thing is that the shape or the appearance or the physical structure changes that is why it is called as a physical change not chemical because its internal composition is the same
It's a physical change why are some people f$#@%ing stupid and saying a chemical change??
Mechanical and chemical digestion are not the same.
