Answer:

A would be Physical

B would be Chemical

and C would be Physical

Step-by-step explanation:

A would be physical because the wood is physically changing

B would be chemical because it's still milk but it now had clumps called curds and a very sour taste

C would be physical because the melted butter is physically changing from melted butter to solid butter.

Hope this helps.
