Moisture in the air around the glass, cup, etc.
The cold lemonade cool the temperature of the plastic cup including the outer side of it. Thereby lowering the amount of water the air can contain, resulting in water condensating - attaching to the cup.
It is called condensation. It is when the Coldness around the cup slows down the moisture in the air ( because moisture is fast in molecular speed) and turns it back into a liquid. The moisture in the air is warm and cooled and slowed down
The cold drink cools the temperature of the cup, therefore moisture in the air condenses (turns from a gas to liquid) on the outside
That's condensation—the water vapor in the air around the cup condenses on its surface because it's cold. So it comes from the air around the cup.
Relative humidity is the ratio of the amount of water air is holding to the amount of water it can hold. The warmer air is, the more water it can hold. Therefore, as air temperature drops, relative humidity increases, even when no additional moisture is being added to the air. If the temperature continues to drop after the relative humidity reaches 100%, the excess moisture gets condensed out of the air. That is why dew forms during the night. The cold cup of water cools the air around it by conduction, so that cooler layer of air in contact with the cup loses its ability to hold its moisture, and the excess moisture condenses onto the cup.
The water vapor in the air. Since the cup is so cold from the ice inside, the vapor in the air when it hits the cup it causes it to make the water on the outsaide of the cup. You'd think it came from the inside, but it doesn't.
Okay don't know why you couldn't search on google but here it is- The warm air around the cold cup cools because of the water and turns into water which is called CONDENSATION, so it lands on the side of the cup. I think...
On a humid day, taking an empty metal cup out of a freezer and placing it on a napkin would cause condensation to form on the exterior of the cup. The cold metal would cool the air around it, leading moisture in the humid air to condense into water droplets. This moisture would then soak into the napkin, potentially making it damp. The overall effect would be a visible accumulation of water on the cup and surrounding napkin, illustrating the principles of condensation.
'Sweat' on a cup is caused by condensation of moisture on the air on a cold surface. Cold causes the air to lose its ability to hold as much moisture. Since coffee is hot, it is increasing the ability of the air to hold moisture. You will only get the sweat on a cold drink. And the air in your house in winter is very dry, so there is not much to condense on cold items.
A Cup of Cold Water - 1911 was released on: USA: 21 September 1911
In a hot cup of water, the water molecules have higher kinetic energy and are moving faster than in a cold cup. This results in the water molecules being more spread out and having increased motion, leading to a less structured arrangement compared to cold water.
