Answer:
Explanation:
Sugar dissolving in water is a physical change. It is because no new substance is formed. Also, the process is reversible – water and sugar can be separated by vaporization followed by condensation and crystallization.
Setting of curd is a chemical change because a new substance(lactic acid) is formed. The curd formed has a different taste than the original substance. Also, once the curd is formed, milk cannot be re-obtained from it. It is an irreversible change.
so option c. Both statements I. and ii. are correct
