Why would a milk bottle probably crack if boiling water were poured into it?
When you pour hot water into a glass bottle, it heats up the glass very quickly. This causes the glass to expand suddenly and the expansion is not uniform over the surface of the glass. The unequal expansion cracks the bottle.This will happen only if the temperature difference is quite high and the glass is weak.It is easier to crack a glass bottle by heating it (like in a dishwasher) and then cooling it immediately by placing it in or under a stream of cold water. Here, the sudden contraction causes the glass to crack.
