Cold air can hold less moisture than warm air. When warm, humid air comes in contact with the cold glass, the air is cooled and water vapor in the air condenses on the sides of the glass.

The water is reproducing - you have to separate the boy and girl molecules to prevent this.
Just kidding. It's condensation; water vapor in the air transfers heat to the water inside the glass (actually the glass itself, which loses heat to the water inside it - but let's not get complicated). At a certain point the vapor loses an amount called the 'heat of condensation' and changes to a liquid state. It collects at the point where this change takes place - namely, the surface of the glass.
Experiment: Try 'breeding' water. Fill a well-insulated mug with ice which is carefully weighed. When the ice melts completely, the water should weigh more than the ice due to condensation on the ice itself. Isn't science fun?

It is called "condensation". Water vapor in the air (warmer than the cup of cold water) comes in contact with the cold cup and condenses on the sides of the cup.

condensation- the water molecules in the air next to the cup are cooled by the cold air coming off the cup and form liquid water.

cos water vapour ard the cup condenses. water can exists as solid liquid or gas, depending on temperature and sum other factors. since ur cup is cold, water vapour ard it also becomes cold and changes to a liquid state, ie condenses. hence little droplets r formed.........=)

Due to its low temperature, it condenses the air directly surrounding the glass, or changes its phase from gas to liquid, by lowering the temperature. The slang term for it is that your glass is sweating.

i think of you're an fool and the water is unquestionably superb to drink. despite the fact that, it extremely is going to in all threat be disgusting after basically sitting there. basically bypass pour your self a effective new chilly cup of water.

These process is known as condensation.Moisture present in air condense and deposite over the glass.The opposite will happen when heat known as evaporation.
