winter holding areas

Sorry Ian, started writing that before you posted

Further ...

Look up 'entropy' and 'latent heat'. When you understand these terms, we can, if required, discuss this further.

;-)

 

[ian jay]

np, Dave. I'm glad someone is awake ;-)

 

[Dave Rothery]

Steam isn't "less dense" water it is effectively "gaseous" water. Ice is "solidified" water. you have to compare these things at a given temperature and pressure. if we are going to pretend "air" is pure oxygen for the benefit of this, it is only a gas because of the temperature and pressure are correct on earth. Lower the temperature far enough it becomes liquid, then solid. this is why water on the top of everest would boil at a lower temperature - theres less atmospheric pressure, so the water molecules can "escape" easier

And, of course, we must respect Avogadro's Hypothesis?

 

[Dave Rothery]

What? Must always go with prawns and thousand island dressing in a sandwhich?

 

[Tim Birch]

lol

Avogadro law, entrophy, sounds a bit like this thread and my tackle box (certainly entrophotic), good stuff though, I'm keeping out of this one, but what about the cryospheric accumulation and ablation?!

 

[Dave Rothery]

I went to a convent school and was constantly being reminded that ablation made you blind!

 

[The Monk]

I should imaging it would Dave,
breaking my balls here mate!

Monk
Thats called Kinetic energy

 

[andrew jackson]

So Ian I take it you are now going to try and explain Ice And steam, and how they are the same density and viscosity, without being personal of course.

 

[ian jay]

Andrew

I'm afraid that it would not help you catch any more carp, because they do not thrive in such states.


Besides, private tuition is ?25/hour

May help?

 

[andrew jackson]

Thanks Ian quick quote from your recomended site "as ice freezes it expands in volume, becoming less dense" nuff said.

 

[Ian Grant]

Oooh my gawd!! - can i ask an unrelated question? What does LOL , and :.O mean on the end of some peoples postings, and Ian what does BTW stand for?

 

[ian jay]

Ian

LOL lots of laughs
;-) or wink or smile
BTW By the way

Andrew

No problem, notice it did not say ..

as water freezes it expands in volume, becoming less dense

I rest my case!

 

[Ian Grant]

Thanks for that Ian, i've been puzzling over
those for ages!

 

[Dave Rothery]

I think the difference is that there has to be a change of state(ie water to ice) before there is a change of density. Do you think anyones still reading this thread??

 

[The Monk]

Yes Dave, nowt wrong with a bit of Glacial and fluvial geomorphology, riveting stuff what?
