Answer 1

$\huge\blue\star\underbrace\mathtt{\underline{\underline\red{Answer}}}$

• 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.
