Question

how is the melting of butter different from Burning of butter​

Answer 1

Answer:

When you cook it over a stove, you are essentially cooking away the water in the butter, only leaving the fat. And that is a chemical change as you cannot easily reverse the process. When butter browns, you are burning the fat, which even further changes the chemistry of the butter

Answer 2

Answer:

It depends on how you melt the butter and to what degree it changes. If it simply melts because you left it outside the fridge, its chemical composition remains the same. Just like when you leave ice to melt into water. When butter browns, you are burning the fat, which even further changes the chemistry of the butter.
