since water freezes at 0 degress celsius the temperature would have to be 0 degress or below.

If ice forms on the outside of the glass cup the temperature of the glass would be 25 degrees Fahrenheit. This is due to the fact that water freezes at 32 degrees Fahrenheit.

The cold drink cools the temperature of the cup, therefore moisture in the air condenses (turns from a gas to liquid) on the outside

Droplets form on the outside of a glass which contains a cold drink because the cold surface reduces the temperature of the surrounding layer of air. This causes water vapour in the air to condense on the surface of the glass.

What your seeing is known as condensation. The water droplets on the glass are "dew"- the surface of the glass in cooling much quicker than the temperature of the air around the glass.

lets say you have a cup of water that is cold. when the air at roomtemperature hits the glass (look below) the air condenses because it is cold. this forms little drops on the outside of cup. this continues till the water is at room temperature them the water proceeds to evaporate. (When a temperature is warm molecules spread out and when they are cold they condense.)

The result is increased temperature, condensation is a warming process. Like if you have an ice cold cup of water, as it gets warmer condensation forms on the outside of the cup...

the glass is cold, so water vapor condenses in the air to the cup

If there is a cold liquid in the glass, water vapor in the air around the glass will be cooled and drops of liquid water will condense.

Assuming the glass cup held a cold liquid, the air closest to the cup will be colder than the surrounding air, causing water vapour in the air to condense into liquid water droplets.

if you would put a glass wine cup into the freezer (ice box) and take it out and run it under steaming hot water, it will break, its just like ice take dircetly from the freezer and put it under hot water you will here it crackle and break!

When you put cold water inside a cup, you cool the outside surface. If the temperature of the outside becomes less than the dew point of the air surrounding the cup, then condensation takes place. This appears as small drops of water on the outside of the cup. Dew point is a function of humidity and temperature. Dew point condensation is the same process that creates frost and fog in certain weather conditions.

Condensation can only occur on a glass that is cold. The reason why condensation forms is because water vapor in the air (a gas) cools and turns into liquid water when it comes into contact with a cold surface.

this is called condensation in the water cycle it forms water droplet because when the liquid turns into gas the particles move and when they spread apart and float away some get stuck on the sides of the glass cup. Then with enough of the gas particles come together turning it into droplets and goes back into water to do it all over again.

The recorded temperature change for an exothermic reaction performed in a glass calorimeter is less than the Styrofoam cup calorimeter. This is because the glass will conduct heat away more than the Styrofoam.

Plastic is less dense than glass, so normally a plastic cup is considerably lighter than a glass cup, although in theory a very small glass cup could weigh less than a very large plastic cup.

When it is turned into condensation. When you have a cold drink, the air is attracted to the cold of the glass or cup, which forms the little droplets! (No, your glass is not leaking!) Glad I could help!!

A glass is made of glass. A cup is made of something that is not see through usually and it has a handle.

The only one of the five that is "below freezing" (32°F) is the 25°F, and ice would normally only form below the freezing point.

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.

A glass cup will conduct heat away quickly - a plastic cup would hold heat the best.
