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.
When hot liquid is poured into a thick glass tumbler, it cracks because the glass is a poor conductor of heat. When hot liquid is poured into the tumbler, the inner surface of the tumbler becomes hot, while the outer surface remains at room temperature. Therefore, the inner surface of the tumbler expands, while the outer surface does not expand. This unequal expansion cracks the tumbler.
The hot water causes the parts of the glass it comes into contact with to expand. This causes stress between the cold and hot area and if this stress is high enough the fabric of the glass shatters.
If glass is to be used to contain hot liquids it should be gradually warmed to the temperature of that liquid so that the stress does not occur.
Matter expands when it is heated. When you pour boiling water into a glass the bottom becomes heated and expands while the rest of the glass is at a different temperature. As the bottom of the glass expands it literally expands and causes stress in the glass that is eventually enough to fracture the bond between the glass molecules, causing a crack. If you heat the glass more evenly it will expand evenly, preventing that stress from happening. Slow and even temperature changes will prevent the breaking.
The boiling water will cause the inner surface of the glass to rapidly expand, while the outer surface would be much slower to expand. It is this inconsistency of expansion that causes stress in the wall of the thick tumbler. Modern glass recipes are less likely to be stressed enough to shatter. Thin tumblers will have both inner and outer surfaces expanding at almost the same time, so are unlikely to shatter.
It is due to uneven thermal expansion. When hot water is poured into the tumbler, the inside surface heats up. As it does so, it wants to expand. But the thickness of the tumbler means that the outer parts have not yet got hot enough to expand. There is, therefore a tension between the inner layers of glass wanting to expand outwards and the outer layer wanting to stay put. It is this tension which eventually causes cracking.
A thick-walled glass tumbler can crack when boiling water is poured into it due to thermal shock. The sudden and extreme temperature difference between the hot water and the cooler glass can cause the glass to expand rapidly and unevenly, leading to stress fractures and ultimately cracking. It is recommended to use tempered glassware or to preheat the glass with warm water before pouring boiling water to prevent this from happening.
During boiling, the amount of energy remains constant as the temperature of the substance stays the same until all of it has converted into vapor. Once boiling starts, the added heat energy is used to break the intermolecular bonds holding the liquid together, rather than increasing the temperature.
Boiling water typically uses thermal energy, which is the energy associated with heat. When water reaches its boiling point, the thermal energy added to the water causes the water molecules to gain enough kinetic energy to break free from their liquid state and change into vapor.
Increasing pressure generally increases the melting and boiling points of a substance. This is because pressure forces molecules to be packed closer together, making it harder for them to break free from each other in the solid or liquid phase. Conversely, decreasing pressure lowers the melting and boiling points.
For boiling to occur, particles in a liquid need to gain enough kinetic energy to overcome the attractive forces holding them together. This causes the liquid to transition into vapor phase as the particles break free from the liquid's surface.
Some glasses break when you pour boiling water in it. To avoid that make sure you read a label that comes with that glass saying it can withstand boiling water or not.
Yes.

If we pour hot tea in glass tumbler the tumbler will expand and break off. So to prevent it we keep a metal spoon in it,as it is a conductor of heat it will absorb heat and prevents the glass from breaking.
solids cannot be poured , they cannot also change shape unless you bend it , break a bit of it or melt it. liquids can be poured. gases can not be condensed down
The strength of intermolecular forces is directly related to the boiling point of a substance. Substances with stronger intermolecular forces require more energy to break those forces, leading to a higher boiling point. Conversely, substances with weaker intermolecular forces have lower boiling points.
These lockers actually use a specialized double tumbler. This means that they will be far more difficult to break into compared to other lockers.

Boiling Point
Alcohol's boiling point is fairly low. At higher pressures, a lot of pressure would build up; this could break the thermometer.Alcohol's boiling point is fairly low.

When antifreeze is poured into your oil, it weakens your oil cause it to break down prematurely and can cause your engine to fail by spinning an engine bearing and even smoke. This is also a sign of a blown head gasket.
