Why does a glass tumbler crack on powering very hot liquid into it?

First you have to understand that everything gets bigger and smaller when its temperature changes. Maybe you remember seeing someone try to put a metal ball through a metal ring. When the ball and the ring are the same temperature, the ball will not go through the ring. If you then heat up the ring, the ball will go through the ring. This is because the ring gets bigger when heated. Thermometers use this same property to measure the temperature outside. You may have seen that some thermometers have either a red or silver line in them that goes up and down as the temperature changes. Other thermometers use what looks like a spring that is attached to a pionter. That "spring" is actually made from two different metals. Since each metal grows or shrinks differently and since they are attached together, the "spring" bends.
Second, and you probably already know this, is that different things can be bend a long ways before they break and other things can bend very little before they break. Most plastic can be bent a long way, or even bent several times, before it breaks. On the otherhand, glass can only bend a little bit before it breaks.
If the glass is thick enough and the liquid is hot enough, when you pour the liquid into the tumbler the glass on the inside becomes hotter than the glass on the outside. The glass on the inside therfore gets bigger than the glass on the outside. This difference in size caused by the difference in temperature causes the glass to bend, not much, but just enough to break.
Hope that helped.Jeff

When hot liquid is poured into a glass tumbler, it causes uneven expansion in the glass due to the sudden temperature change. This uneven expansion can create stress in the glass, leading to cracks or fractures. Additionally, the sudden change in temperature can weaken the glass, making it more susceptible to breaking.

Why does an ordinary glass tumbler crack if very hot water poured into it?
When hot water is poured into a cold glass tumbler, the sudden temperature change creates thermal stress in the glass. This stress can cause the glass to crack or even shatter due to uneven expansion of the glass material. It is recommended to avoid extreme temperature differences to prevent this from happening.
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.
Why a thicks walled glass tumbler cracks on pouring boiling water into it?
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.
Why does a glass tumbler break when boiling water directly poured into it?
Pouring boiling water directly into a glass tumbler can cause it to shatter due to thermal shock. The sudden change in temperature causes uneven expansion and contraction of the glass, leading to stress and eventual breakage. Using tempered or heat-resistant glass can help prevent this.
Is the center of gravity of a glass tumbler closer to its bottom or mouth?
The center of gravity of a glass tumbler is typically closer to its bottom because the bottom is usually wider and heavier compared to the mouth. This means that the majority of the glass's mass is concentrated towards the bottom, shifting the center of gravity in that direction.
Does a glass tumbler containing hot water crack if you cool it by pouring cold water on it?
Yes, it is possible for a glass tumbler containing hot water to crack if you cool it rapidly by pouring cold water on it. The sudden change in temperature can create stress within the glass, causing it to crack or shatter. It is recommended to gradually cool the glass to prevent this from happening.

Why shouldn't you pour a hot liquid into a cold glass?
The hot liquid could crack a cold glass.

What is the name for a stemless glass?
tumbler
Why does a glass tumbler containing ice-cool drink show droplets of water on its outer surface?
When the cold drink is poured into the glass, the air around it cools down quickly. This causes the water vapor in the air to condense on the colder surface of the glass, leading to the formation of droplets. The droplets are essentially water from the air that has condensed on the chilled surface of the glass.
Why does a glass tumber containing hot water crack if you cool it by powering cold water on it?
Because you're cooling down, thus shrinking the glass, outside MORE than the inside (in contact with hot water)

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.

What is another name for a small whiskey glass?
It's called a shot glass.
Why does a experienced housewife will always place a metal spoon in a glass tumbler before pouring hot tea in to it?
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.
