why a glass filled with a cold beverage seems to “sweat”. Would you expect more sweating inside a house?

It depends on the relative humidity. The location with more relative humidity will cause more "sweating" or condensation on the outside of the glass. \n\nThis will usually be indoors, since it is usually drier indoors, thanks to air conditioners in the summer, and heaters in the winter.

Heat will make molecules expand.  Expanded molecules will take up more room and will affect the volume.  A hot liquid will take up more volume, especially in small containers, like pipettes.  It will give you a false measurement.\n\nFor accurate results, the glassware is calibrated with liquids at the specified temperatures.

Does it have to be a material? the best solution for this would be to have 2 cans one just inside the other with a compleat vacume between them, as there is no air to transmit the heat between them the liquid inside wont change tempreture.\n\nthis is the principle of a thermos flask,\n\nif you need an actual material, somthing that would trap air to stop it from moving and spreading the heat such as glass fiber like you might have in your loft\n\nhope this helps

gases are in general more soluble in cold liquids, so less of the dissolved carbon dioxide is lost from an iced glass of Coke vs. one at room temperature.  I've also noticed that drinks with artifical sweeteners tend to go flat faster, but I have not figured out yet whey it seems like the presence of large amounts of sugars affect the solubility of the CO2 yet.

Humidity adds to the heat as well as the cold. \nIf the air is saturated with water, and it's also cold outside it will make it so much colder. When it's hot outside and there's high humidity it also makes it hotter, you wouldn't think so, but it feels a lot like a sauna.

condensation--the difference in temperature from the outside and the water in the glass causes the water to condense and it gets wet.

If the dry ice is to sublimate, the room you keep it in will have to ADD heat to the dry ice, so the answer is dependent on the rate of heat flow into the room.  If it were perfectly insulated, the ice would sublimate only to the extent that the interior was cooled to the temperature of the ice, after which all heat transfer and change of state would cease.  BTW sublimating is not 'melting'\n\nEven without the room, the time to sublimate would not only depend on the ambient temperature, but also the geometry of the ice, a sphere taking the longest time and a thin plane of ice taking the shortest.

I grew up in a dry climate so my body learned that sweating would result in cooling.  I am now in a humid environment and my body produces much more sweat than is useful.

Hmmmmmmm never asked but I am assuming the wetness and the heat of the mouth! Because you can change how that feels by drinking something hot or cold to make it feel different!

You might be sensitive to some ingredient.\nI've seen people get hives, turn red and splotchy around the eyes, break into a sweat and get weak, etc after drinking even small amounts. These same people will have no adverse effects with a different drink on a different night.

whaddaya got?? what ever, just gimme a couple of shots of sum strong stuff!!\n\n\nand by that, i mean cold coffee

High humidity makes the temperature seem warmer.\n\nAlso, when something condenses, as in the water in the clouds, it gives off energy often in the form of heat.

if the cold thing is cold and crystaline, like pyrex or ice, the object cracks because of rapid localised expansion.\n\nIf it is really really cold, the water will crystalise.\n\nIf cold water hits something hot it forms little drops with a protectice steam jacket and they bounce around for ages, a cool experiment for home on a hot frying pan. (only uses drops of water though)

Yes, glass is technically a supercooled liquid. It has an amorphous structure and it actually flows under gravity. Windows in old buildings are thicker at the base than at tha top due to this property.

As my college chemistry professor said:\n\nOn a warm day, ther-mo-dy-nam-ics tells you that your cold beer is not going to get colder, it's going to get warmer so you better drink it sooner rather than later.\n\nThus, heat flows from hot to cold, not cold to hot.\n\nAnother way to look at it this.  Cold is not the presense of something, it is the absense of something.  It is the absense of thermal energy.  At absolute 0, there is now thermal energy in the system.  While placing something hot in the system will make the hot thing colder, it is because the thermal energy is migrating from the hot thing to warm up the cold surroundings.

the room will warm up, the "cold" is created by moving "heat" to the coils.  unless the fridge is a perpetual motion machine, the heat created will be greater than the cold created and the room will warm up.

interior of cup expands faster than exterior of cup due to poor thermal conductivity of the cup material.\n\nglasses that are thin enough will not suffer this problem because heat can conduct thru thin materials easily so that thermal expansion is more or less equal on the interior and exterior.\n\nyou can also force one of your glasses to break by cooling the glass with ice water, dumping the ice water away and then dousing the glass with boiling water. try not to hurt yourself.\n\nbicycle tire ruptures due to a simpler explanation. the tire cannot withstand increased pressures that occur when a gas is heated in a closed system.
