It would depend on the temperate of the room, the amount of water, the temperate of the hot water and the thickness of the glass. (Also on the humidity, the elevation)
So it's really impossible to say.
I assume you mean a typical 250 ml glass, and the air was room temperate, normal pressure, humidity, fairly typical elevation...
But, I'm still not sure what temperate of water you mean, which is one of the most important factors.
30 minutes perhaps?
Condensation occurs when warm, moist air comes into contact with a colder surface, causing the air to cool and release moisture in the form of water droplets. In the case of a warm glass of water, the glass cools the air around it, leading to condensation on the outside of the glass.
Styrofoam because it has a thick layer and is a good insulator.Paper and plastic are could alternatives but Styrofoam would work better, therefore glass would be the worst one to use because it would only keep it warm for a couple of minutes.
A plastic cup will not keep hot water warm for a significant amount of time. It is not an effective insulator and heat will dissipate quickly. It is recommended to use a thermal mug or a container specifically designed to keep beverages warm for longer periods.
Glass is a poor insulator, so it does not retain heat as well as materials like ceramic or stainless steel. However, double-walled glass designs can help to keep a hot drink warm longer by creating an air pocket that acts as insulation between the layers of glass. Additionally, using a lid to cover the drink can further help to retain heat.
A glass cup would keep water warm the longest because glass is a good insulator and retains heat well compared to plastic, paper, or styrofoam which are poorer insulators. This is because glass has a lower thermal conductivity compared to the other materials, so heat escapes more slowly.
Do you mean the actual glass itself is warm or the water inside? If the water is warm then its a glass of warm water What is the noun you want to modify -- the glass or the water? It's hard to imagine a warm glass containing cold water, but I suppose it's possible.
Cover it with a thick lid.
No, a galss cup does not keep any drink warm long.
for about 3 hrs
because steel is goood
they keep warm because they put water proof warmers in their swimming caps which warms their whole body

they keep warm by sleeping in long grass.
When warm water is poured into a cold glass, thermal stress is created due to the uneven heating of the glass. This stress can cause the glass to crack or shatter due to the expansion and contraction of the material. Rapid changes in temperature can lead to the glass failing under the strain.
It Melt Bcuz The water is Warm So it Melts The Ice && Then The Coldness Make the Warm Water Cold
