Hey Mate,
Here's your answer
1. Physical change refers to a change in which the molecules are rearranged but their internal composition remains same.Eg.melting/freezing of water
2.Chemical Change is a process in which the substance transforms into a new substance, having different chemical composition.ExampleTearing of paper, , cutting of trees, etc.Burning of wood/trees/paper, rusting of iron, setting of curd,
Hope it helps you
If yes,mark it as B.R.A.I.N.L.I.E.S.T
