mamluv u best teacher just wanna ask if an egg is cooked is it chemical change as physical change has the same arrangement of atoms but in chemical a new substance is formed making a new arrangement of atoms making new substance
But mam in physical change u said dissolving sugar in water is reversible as when we boil it we get back sugar crystals, but when we boil it won't it become caramel, isn't that a new substance
20:20 Cutting grass or pulverizing a rock are examples of irreversible physical changes.

But mam in physical change u said dissolving sugar in water is reversible as when we boil it we get back sugar crystals, but when we boil it won't it become caramel, isn't that a new substance
With crystallization we can turn it back
But sugar is converted into different shape and size again and again. If you need sugar crystals it can use the method crystallization.
