If we boil the milk it pour down then why if we boil water it does not...
MILK IS NOT SIMPLE LIQUID. IT CONTAINS MANY CONSTITUENTS OF FATS AND CASEIN. MILK OVERFLOWS BECAUSE IT CONTAINS ENTRAPPED AIR .THE AIR EXPANDS ON HEATING AND TENDS TO ESCAPE LIFTING THE SURFACE OF MILK.ONCE ALL THE AIR WOULD BE EXPELLED THE BOILING WILL BE REGULAR. THEN SECOND BOILING WOULD NOT LEAD TO OVERFLOW.

     WATER DOES NOT CONTAIN ENTRAPPED AIR . SO IT SIMPLY CONVERTS INTO STEAM OR VAPOUR  WITHOUT OVERFLOWING..
HOPE IT WILL HELP U A LOT...

Thirty yards of board fence, nine feet high. Life to him seemed hollow and existence but a burden. Sighing, he dipped his brush and passed it along the topmost plank; repeated the operation; compared the insignificant whitewashed streak with the far-reaching continent of unwhitewashed fence and sat down on a tree-box, discouraged.Jim came skipping out at the gate carrying a pail and singing. Bringing water from the town pump had always been a hateful work in Tom’s eyes before, but now it did not strike him so. He remembered that there was company at the pump. Boys and girls were always there waiting their turns, resting, trading playthings, quarrelling, fighting. And he remembered that although the pump was only a hundred and fifty yards off, Jim never got back with bucket of water before an hour and even then somebody generally had to go after him. Tom said: “Say, Jim, I’ll fetch the water if you’ll whitewash some. I’ll give you a marble.” He shook his head fearing aunt Polly’s slipper.On the basis of your reading of the passage, choose the correct option:Q. Bringing water had always been a hateful work in Tom’s eyes because ____________.
