can you tell how hot water is by how high steam rises of the surface?

Answer 1

yes and no
if the water is heated in a cold atmosphere the steam will rise at a lower temperature than if the water is heated in a warmer atmosphere
hope that helps

Answer 2

No, is the simple answer.

Steam is a gas and what most people think of as steam is only water vapour that is actually cooling and condensing back into liquid form because it's in contact with air molecules that are colder than it is. Because steam is a gas, it interacts with other atoms/molecules as one. If two gases are mixed together, both of different densities, then the general rule is that one gas will "float" above the other. Liquid Carbon
Dioxide is a lovely example. When it's cold and subliming (that is transferring from a solid to a gas without going through the liquid phase) we see it laying low on the ground. With steam it is hotter than most air molecules by a large degree therefor it will try and get above them. But to get to the actual question, steam generally is only formed at very close to 100 Degrees Celsius so it is safe to say it's temperature is firly constant. The only thing that would determine how high steam rises is the ambient (or surrounding) air temperature.

Answer 3

If you can see the steam there is no rise in temperature.
It just evaporates faster unless pressurised.

Answer 4

I don't know but it must be possible because meteorologists can calculate cloudbases. Ask a Met man(or woman)

Answer 5

Perhaps an educated person could..but your question was "can you" my answer is No I can't

Answer 6

No!
