Glass expands at different rates. This rate is called a coeficient of expansion (COE). The higher the number the more it expands as its temperature rises. Glasses with low COE's can withstand heat much better than those with high COE's. When you pour hot liquid in a glass container with a high COE (90) quickly it can expand so much, so fast that it breaks. If you do the same thing in a Pyrex container (COE 32.5) it expands less and can take the stress without breaking.

What materials are used to insulate Themos's?
Materials commonly used to insulate thermos include foam, glass, and vacuum-sealed chambers. These materials help to reduce heat transfer, keeping hot liquids hot and cold liquids cold for an extended period of time.
Why is hot water poured to a drinking glass more likely to break the glass?
When hot water is poured into a drinking glass, the temperature difference between the hot water and the glass can cause uneven expansion, leading to stress in the glass material. If the stress exceeds the glass's structural integrity, it can result in the glass breaking. Rapid heating can also cause thermal shock, further increasing the likelihood of the glass breaking.
If a hot piece of thick glass is dipped in cold water it breaks give reason?
When the hot glass is suddenly exposed to cold water, the outer layer of the glass cools and contracts rapidly, while the inner layers remain hot and expanded. This creates stress within the glass, leading to unequal distribution of forces and ultimately causing it to break.
What causes a glass bowl to get hot when its on a hot plate?
The ordinary dish has a relatively high coefficient of thermal expansion, relatively low thermal conductivity, and is brittle with no yield point. The bottom will get hot while the top remains cool causing tension stress on the top surface which can break the glass due to it relatively low tension strength, especially if it is scratched
Does glass break if it gets too hot?
Yes, either because of uneven heating or expanding larger than the frame can accommodate. Glass that is subjected to overly hot items (as in a microwave) will often crack first rather than melt. Temperatures as low as 200 degrees F can cause cracks in the edges of ordinary window glass.
What glass can withstand hot liquids?
Borosilicate glass is known for its ability to withstand hot liquids due to its high resistance to thermal shock. This type of glass is commonly used in laboratory glassware and some types of kitchenware. It is also more durable and less likely to break when exposed to drastic temperature changes.
Will liquids stay hot in glass?
Yes, liquids can stay hot in glass containers because glass is a good insulator and retains heat well. However, glass may not retain heat as effectively as some other materials like metal or ceramics. It's important to be cautious when handling hot liquids in glass containers to avoid burns or breakage.
Why should you never pour hot liquids into a drinking glass?
Pouring hot liquids into a drinking glass can cause the glass to expand rapidly, leading to cracks or shattering. This sudden change in temperature can also cause the glass to break, posing a safety hazard. It is better to use heat-resistant glassware or let the liquid cool slightly before pouring it into the glass.
Which cups glass ceramic plastic metal are best suited for keeping hot liquids hot or cold liquids cold?
metal
Why should you never poor hot liquids into a cold drinking glass?
Because the glass shatters
Can you keep hot dishes on glass tables?
yes it has to be very hot for glass to break or melt
Why do we prefer to use glass utensils to serve hot liquids rather than using metal utensils?
We prefer glass utensils for serving hot liquids because glass is a poor conductor of heat, which helps prevent burns when handling the containers. Additionally, glass doesn't react with acidic or hot substances, ensuring that the flavor and quality of the liquid remain unaffected. Unlike metal, glass also does not leach any metallic taste into the liquids, making it a safer and more suitable option for serving hot beverages.
Is it safe to add hot liquids to milk glass?
It is a very delicate variety of glass. I would advise against it.
Why should you never pour hot liquids into a cold drinking glasss?
you can if you put a spoon it the glass first before pouring in the hot liquid, otherwise the glass might crack
Why does the hot glass of a kerosene lamp cracks when wet with water?
The glass of a kerosene lamp while glowing is hot. When water falls on it, there is a sudden change in temperature, which causes the glass to break.
Why are microscope slides made of glass?
they are made of glass because it is transparent and nonpermeable so no liquids can pass through it it is hard aswell so it will not break easily
Is a buret used to heat flammable liquids?
No, a buret is a glass tube with a stopcock at the bottom that is used for delivering precise quantities of a liquid. It is not designed for heating liquids, especially flammable ones, as it may break due to thermal expansion or cause a fire. Use proper lab apparatus like a heating mantle or hot plate for heating flammable liquids.
