hey...
Physical change refers to a change in which the molecules are rearranged but their internal composition remains same.
Chemical Change is a process in which the substance transforms into a new substance, having different chemical composition
.ExampleTearing of paper, melting/freezing of water, cutting of trees, etc
Chemical change.....Burning of wood/trees/paper, rusting of iron,
