Water might disappear on a cup through evaporation. As the water sits, it begins to turn to a gaseous state and rises away from the cup.

How many ounces in 1 cup water?
1 cup = 8 fluid ounces, regardless of what's in the cup. Even if it's empty.
Why does it take longer to heat a bucket of water than a cup of water?
Because there is more water in a bucket than in a cup, and more energy has to be put into the bucket of water than the little cup of water to bring them to the same temperature.
Why a cup crack when it is filled with boiling water?
When a cup is filled with boiling water, the heat from the water caused the material of the cup to experience thermal expansion. If the cup is badly made, then different parts of it will expand to different extents and this will create stresses in the material of the cup causing it to crack.
What cup is easier to hold with hot water a plastic one or metal?
a styrofoam cup. i tried it on my science project
Why does water stick to the outside of a cup when it's hot?
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.
What part of the water cycle does the water on the outside of a cup show?
The water on the outside of the cup is an example of condensation.
Why does water not form on the outside of a cup when you have a hot drink?
Hot cup evaporates water while cold water condenses water .
What is it called when water builds on the outside of a cup?
Condensation
Why is it that when a cold water is introduced into a cup water molecule are seen outside the body of the cup?
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.
Why would droplets of water form on the outside of a cup?
rain
Would droplets of water form on the outside of a glass cup?
yes.
When a cup is sweating is the water colder or warmer than the outside?
A sweating cup is colder than the air which surrounds it.
When I pour cold lemonade in a plastic cup why is there water outside my cup and where did that water come from?
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.
How long a cup of water outside takes to evaporates?
This depends on many factors.
What happens to water in a cup when left in the sun?
If you happen to leave a cup of water outside for a few hours it will evaporate and melt once it melts it will turn into gas
Why would drophlets of water form on the outside of a glass 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.
When a cup is filled with water with a card on top of it is turned upside down the water does not fall out why?
because the pressure on the inside is less than the pressure on the outside of the cup, so the card remains on the bottom of the cup when it is tipped over.
