Glass could be termed as a liquid at room temperature which is why it needs such a low stress to creep. (Many Glass frames, older than 50 years, arevisiblythickerat the bottom compared to the top). Glass can be found in awateryliquid form at various temperatures from 1000 C to 10000 C depending on heating rates and chemical composition. Pretty confusing stuff glass is.
Water expands as it begins to freeze, and ice takes up more space than the original volume of water. Freezing water in glass containers is hazardous. Depending on how the water freezes, it could break or shatter the glass.
One list of measurements is linked below. Pure glass would be quartz (SiO2) whose freezing (melting) point is 16500C, and with the addition of colorants and other "impurities", the melting point can apparently be brought down to ~5000C.
no its not safe or smart because all it would do is freeze over the glass and crack!
It is not recommendable - the glass may be broken by freezing of the foods.
You mean, can you put something in glass and freeze it? Yes, if there's enough expansion room in the container.
Yes, it does melt.
No. Every substance has its own freezing and boiling temperatures, and they're rarely the same as the freezing or boiling temperature of any other substance. Here's something to consider: You're sitting in your easy chair, enjoying a glass of water and breathing comfortably. Let's just say the temperature is about 72° in the room, more or less. That temperature is above the freezing point of the water in your glass, but below its boiling point. So the water is liquid. But 72° is lower than the freezing point of glass, so the glass tumbler is solid, and it's holding the liquid water very nicely. 72° is above the freezing point of air, and even above its boiling point, so the air in the room is in the state of gas, (which makes it much easier to breathe). If the temperature in the room were to change drastically, however, you could easily have steam, or liquid glass, or solid air.
No. It will get cold but it will not freeze.
Sea water will not freeze.
Yes, the glass is made up of millions of parts which is combined to one thing, so when they "freeze" or get "colder" it tends to shatter more easily.
Vegetable oil can't freeze.
The glass may break.
I had a 1975 Chevy pickup truck that I was welding on the door. The molten steel fell on the window and fused itself to it. I ruined the glass and learned that you can indeed have metal freeze on glass.
Of course. Glass won't crack!
Coke that has been poured into a glass will freeze faster than coke that is in an unopened can. Pressure of the can will prevent it from freezing.
Yes they can.
I assume you mean the water in the cup. Foam is a better insulator than glass, so it should be the water in the glass cup.
The metal paper would freeze more because it is a good conductor hence easily lose heat.
Assuming they are the same or similar shape and volume, water in glass would freeze first, then plastic then foam. Foam allows transfer of heat out of water more slowly than plastic and the glass probably has the highest rate of heat radiation of the three.
Pyrex is perfect for microwaving because it is made of glass. Glass is safe to go in the microwave and it will not contaminate your food.
I'm just guessing no because that should be illegal.
if you add it will stay liquid but if you remove it will freeze
No - Alcohol won't freeze, so you can't make a frozen shot glass out of booze. However, you can either use a mixer (fruit juice, tonic water, etc) and freeze it in the shot glass mold, or make a gummy shot glass by melting 4 ounces of gummy candy in the microwave for 1 minute and then pouring that in the mold (4 ounces per glass). Regardless of what kind you make, freeze the mold and contents until solid, then pop it out and fill it with whatever beverage you'd like to imbibe in.
