Explanation:

because curd is formed from milk and we can't get the milk again

because curd is formed from milk and we can't get the milk again bakingo chapati is a chemical change because chapatis formed from flour and water so we can't get the flour and water again

because curd is formed from milk and we can't get the milk again bakingo chapati is a chemical change because chapatis formed from flour and water so we can't get the flour and water again dissolving is a chemical change because we can get it by evaporation again for example if we dissolve sugar in water we can evaporate it and then we get sugar again and water get condensed
