explain why melting of ice is a reversible change curding of milk is irreversible change
​

Answer 1

Answer:

Melting of ice is a reversible change because on freezing, the melted ice changes back to its solid form. On the other hand, curdling of milk is an irreversible change because on curdling, milk changes to curd and cream, and gets spoilt when not refrigerated, and cannot be changed back to milk by any process.
