1 . a ) Physical change b) Chemical change c) Chemical change d ) Physical change 2) Cooking food is a chemical change because when food is cooked new substance is formed and it is irreversible reaction . 3 ) No new substance are formed in physical change . Most of the physical change are reversible. Example - Boiling of water On other hand new substance are formed in chemical change. Most of the reaction of chemical change are irreversible. Example- Cooking food .

Method of teaching is too gud sir🙏🙏🙏
