When water vapor cools, it loses energy and begins to condense into liquid water droplets. This process is known as condensation and is responsible for the formation of clouds, fog, and dew.
Water vapor in the air can condense on a cold window, forming droplets. This is because the cold temperature causes the water vapor to cool and change from a gas to a liquid state.
You can breathe in either. Given a normal environment both hot and cold water will evaporate and become water vapour (change from a liquid to a gas). All else being equal the hot water will evaporate faster, but the cold water will still evaporate. For example, when you sweat, your sweat is not particularly hot, but it is the evaporation of the sweat that cools you down. You can therefore breathe in the water vapour from either hot or cold water. Just for absolute clarification - the above assumes the questioner is not asking if you can breathe under water; which clearly you can't unless there is something a little fishy about your character! :-)
The water vapour condensed on the windows. The vapour rising off the acid made me choke.
its called a 'vapour trail' it happens when the jet engines eject the gas from the rear of the engine and the gas reacts with the vapour (water vapour-like steam form a kettle) in the atmosphere. these vapours then go on to produce what we know as clouds when they build up in layers! (but different to the clouds made by the sun and water evaporation!!)
When hot water is mixed with cold water, the overall temperature of the mixture will be between the initial temperatures of the hot and cold water. The hot water will transfer heat to the cold water, resulting in a gradual temperature equilibrium.
it becomes water vapour in the air
The air that you exhale contains water vapour. When you exhale during a cold day, the relative humidity increases. Relative humidity is actually the percentage of the amount of water vapour in the air.(the maximum amount of water vapour that the air can hold at that temperature) The colder the air, the less water vapour it can carry. When exhaled, air mixes with cold air, the temperature of the exhaled air drops, but there is more water vapour. When the air becomes saturated, (relative humidity is 100%), the extra water vapour will condense, allowing you to see your breathe on cold days.
When a cold spoon is placed near the vapor of boiling water, the water vapor cools down and condenses into water droplets on the surface of the spoon. This happens because the cold temperature of the spoon causes the water vapor to lose energy and transform back into liquid form.
Steam is water vapour - just a very hot form of it.
Yes it is, this is due to the fact that the solubility of water vapour in air decreases with temperature and so the water vapour will condense on any cold surface.
Water vapor condenses in a cold condenser tube.

your water vapour from within your body
The warm water vapour in your breath condenses into water droplets when it hits the cold air.
When you breath out, you breath out some water vapour. This is normally invisible, but cold air cannot hold as much water vapour compared with warm. This causes some of the water vapour to condense in mid air in front of you, forming 'the cloud'!

It becomes hotter vapour.
