Expert Answer
In a chemical change, the changes are permanent which can usually not be reversed to form the original substances.
Hence changing the milk to curd is chemical change as it can not reverse.
In a physical change, the changes are temporary and can be easily reversed to form the original substance.
Hot milk is becoming cool due to the change in temperature as this can be reversed hence it is a physical change.
