Why is conversion of milk into curd considered a chemical change in advanced questions?

Answer and explanation

Correct answer: Because curd is a substance with new properties

The governing criterion for a chemical change is the formation of one or more substances with different properties. During curd formation, microorganisms convert some milk sugar into lactic acid, changing the taste, texture and acidity and producing curd with new properties. The process is not merely cooling, changing containers or freezing the same substance. Therefore option A is correct, even though the change occurs gradually and may not be easily reversed.
