Whi many are, many are not (iodine vapour is quite easily seen, for example, where water vapour is not).
If you look carefully at a boiling kettle, water vapour is the white vapour you can see. Steam is actually the invisible short section between the spout of the kettle and the start of the water vapour.
a pure gas of oxygen and hydrogen The water cycle is driven by the Sun's energy. When water evaporates, it turns into the invisible gas called water vapour.
Clouds are formed from water vapour - which is virtually invisible to radar.
Water vapor is invisible water (kind of like mist) that floats around in the air.
the difference is that water vapour is just one particle that joins together with more and more to form steam
'When liquid water changes to an invisible gas it is called evaporation. The water is turned into water VAPOUR. You can remember this by remembering the word vapour in eVAPOURation.
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'!
Yes. Steam is the gaseous form of water, and it is invisible. When it meets the colder air it starts to condense, and forms water vapour, which is visible.
Actually, the steam part is not actually steam, but water vapour. If you look closely at a boiling kettle, there is a clear space between the spout and the actual (steam). That clear space is the steam, which is invisible. What appears afterwards is water vapour.
Clouds are made up of very small droplets of water. Water vapour is invisible, a water vapour cloud could not be seen.
Water vapor is the gas form of water, typically formed when liquid water evaporates or sublimates. It is colorless, odorless, and plays a crucial role in Earth's water cycle, as it can condense to form clouds and precipitation.
1. Vapour is formed when a liquid is boiled- like steam would be the vapour form of water. 2. If you take a small quantity of water and spray it thru a fine nozzle under high pressure, the resultant spray, which would be made of very fine droplets of water would be called a mist.
