Question

making cottage cheese from milk is which physical or chemical change
​

Answer 1

Answer:

I must disagree with the first answer; making cottage cheese from milk is a

chemical change, since new substances are formed. The lactic acid causes

the curds (solid part) to separate from the whey (supernatant liquid) and both

these are not the same chemically as the original milk. Mixing them together

will not give you the original milk back - the curds and whey are the products

of the reaction and different from the original milk.
