b. Cheese is removed from curdled milk by the process of decantation.
c. Separation of sugar from tea can be done by filteration.

Answer 1

No these are wrong methods none of them is correct they need to be separated from another method

Answer 2

The methods which Divya suggested to separate one particle from the other in below given three cases are absolutely wrong.

1. Pure water cannot be obtained from sea water write the process of filtration because sea water contains dissolved salts which cannot be separated through normal filtration procedures.

2. In the similar way cheese is not removed from curdled milk through decantation because extraction of cheese from sugar is a different process of cooking.

3. Separation of sugar from tea cannot be done through filtration because even tea contains dissolved amount of sugar which cannot be separated through normal filtration process.
