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.

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.

its called condensation and its caused from cold and warm air hitting each other.

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

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.

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 ice cubes absorbs heat from the surrounding air, cooling the glass so atmospheric water-vapour condenses on the outer surface of the glass cup.

a condensation of water will form on the outside of the metal container. What really happens is the frigid temperature of the cup actually cool the air down that it comes in contact with and water droplets form.

The water droplets themselves are just water droplets, precipitates, runoff.They got there through condensation, the change of a gas state back to a liquid state, and the reverse of vaporization.

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.

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!!

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.

Condensation and Dew are related because Dew is practically Condensation since Condensation is Gas to a liquid. Humid turns to liquid. For example a cold glass of water that is outside for a long time. When you come back out you will see droplets on the side of the cup.

The ice cools the water and the container. This causes water to condense on to the surface from the air.

Hot cup evaporates water while cold water condenses water .

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.

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

The outside of the cup is warmer drawing in condensation from the air and your drink.

That is because the dry ice is so cold that it even spreads outside of the cup

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.
