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.
Why a crack in a glass vessel often shines like a mirror?
cuz crack in a glass means there wud be a layer of air in the crack.thus when light rays muv 4m glass to air that is denser to rarer medium,as we all knw, Total internal reflection occurs.as a result,light rays get refleted to our eyes,so a shine seems to appear on d crack.

Why a thicks walled glass tumbler cracks on pouring boiling water into it?
The boiling water causes the inside surface of the thick glass to expand rapidly. But the outside of the glass expands at a much slower rate, as it takes time for the heat from the inside to reach the outside, and the expansion to equalise. It is this difference in expansion that can cause the glass to break.
What is glass expansion?
A thick Glass tumbler crack when hot water is poured into it,because the inside of the tumbler expands more rapidly than outside and causes strain in the glass As result of this a type of glass known as pyrex is used for making lab beakers and flask to avoid above effects.

Why does a glass tumbler crack when you suddenly pour hot tea into it?
When we pour very hot water into an empty glass, the inner surface of the glass will expand as matter expands when heated. But the inner surface of the glass will expand more than the outer surface of the glass because more heat is applied to the inner surface of the glass.
What is a glass tumbler?
Locks have what are called tumblers. Your ignition key turns the lock within the tumbler assembly. The tumblers fall into the groves on the key allowing it to turn. Insert the wrong key and the tumblers are not aligned properly and the key will not turn.A tumbler is a flat-bottomed glass with no handle, foot, or stem.

Why does a glass tumbler break when boiling water directly poured into it?
When heat is applied to something, it tends to expand. When you pour hot water into something made out of glass, only the inside dilates, and the outside doesn't, since its temperature is cooler. If the insides enlarges but the outside doesn't, it cracks. For this reason thick glass is more likely to crack, and thinner glass is less likely. Also, the bottom of the glass could expand, while the top doesn't (if the hot water goes straight to the bottom). In any case, the temperature is higher in one part of the glass and lower in another, so one part expands and another stays the same size.
