What happen when we boil water and expose the steam to a cold surface?
When we boil water and expose the steam (water vapor) to a cold surface, it will condense into tiny drops of water on the cold surface. If you can see the 'steam'rising above the water, it has already condensed into tiny droplets of water in the cool air.

Why it is not possible to produce steam in open vessel?
Steam is produced when water vapour condenses in air. If the air in a vessel is cold enough, steam can be produced in it, open or closed. Mostly, say in a saucepan, the air above the boiling water is heated in the process of boiling, so it is too hot for the water vapour to condense in the saucepan. However, if you pour some very hot water into a cold bath (for example) you may well notice clouds of steam forming above it.
What is the function of the cold water in Newcomen's steam engine?
The cold water is used to cool down the steam in the cylinder of the engine. A jet of water from the cold-water reservoir enters the cylinder at the end of the up-stroke. This creates a vacuum due to the condensation of the steam. The pressure of the air above the piston now forces it down, raising the pump rods. This allows the engine work on indefinitely.(check the related link for an illustration)

Why does hot water steam when it's thrown out of a cup in a cold temperature?
Hot water always steams, but when it is cold, the steam quickly converts to water droplets, and thus becomes visible. Pure steam is invisible.
