no. when water boils it is a physical change, because the actuall chemical structure is still H2O, it is just in the form of steam.
No, they are still in H2O form. Change of state does not change the chemical nature of molecules.
When water boils, the bubbles are made of water vapor. Water is changing from the liquid phase to the gas phase, but it doesn't change all at once, so you get bubbles of gas inside the liquid. The phase change will happen first at the location where heating is taking place, so if you have a pot on a stove, the bubbles will form at the bottom of the pot, and then rise to the top.
oxygen? NopeSteam. Steam is water in gas form. Boiling water reaches a temperature of 212 degrees and it begins to turn to steam. Interesting property of water is that no matter how hotter you turn up the heat, the water temperature remains at 212 degrees.
No, that's impossible. Water becomes steam when it boils, and that's just water in the gas phase. Water is made of hydrogen and oxygen. There are no carbon atoms there to form carbon dioxide, and carbon dioxide contains no hydrogen.
Yes. And this is the cause of fogs. Fogs are just dust particles on which water is present. There are no fogs in America as it does not have dust particles.
Water vapour
Water vapour
Water vapour
Below the surface
Some get it from rivers (rain falling elsewhere), some form fogs, some get it from rain and some from snow.
It is the water vapor that is formed inside the bubbles. Water is lost in the air in the form of water vapor.
It boils at 212 & becomes steam.
Water vapor (steam) is inside the bubbles that form inside boiling water. The bubbles that form prior to boiling are mostly dissolved gases escaping from the water.
Steam is water molecules in vapor form
Water is vapor or steam at 213 0F at normal pressures.
The Dew Point because you have to have the ewpoint to cause fog to form.
