They cannot! The definition of the verb "to boil" precludes it.

No but it's the only thing on earth I know of that has the ability to cause a propeller attached
to a yacht to boil water.

Boiling temp. There's that boil word again. You're still guilty
of using a word that means to add heat. You can combine it
with another word but that doesn't change the meaning of
the word boil. As I argued with Gilligan, and he finally concurred,
a propeller does not add enough heat to the water to boil it. It
only lowers pressure in some cases enough to vaporize water and
cause cavitation, so to say a propeller boils water is just plain wrong
according to the definition of the verb "to boil".

For a displacement boat, a heavy deep-keel boat, the maximum speed a given hull can attain from wind power is called "hull speed"
and is largely dependent on the waterline length of the boat. Hull speed is expressed as 1.34 X the square root of LWL, or length of
waterline. If a cruising sailboat has a waterline length of 36 feet, she should be able to sail 1.34 x 6, or approximately eight
knots.

When an Atomic 4 explodes into flames I bet the heat conducted through the
propeller shaft tot he propeller can boil water.

How do you feel about the current usage of the terms, "Decimate" and

Inquiring minds want to know. )

When water goes from liquid to vapor it is vaporization.

Boiling is a subset of vaporization. vaporization caused by heating.

When water goes from ice to vapor it is sublimation. It is not boiling.

Does frozen carbon dioxide cause water to boil when you throw it in? Is the
carbon dioxide boiling? Is it sublimating?

Decimate, my usage of that is mostly in digital signal processing:
decimation in time or frequency. Decimate to reduce by 1/10, which is not
true in DSP. The modern usage is wrong too, as is the use of quantum. A
"quantum leap" is actually the smallest leap possible, as quantum is the
smallest divisible unit. Here the use means the exact opposite of the word.

A clip is a clip as in the clip for the Garand Semi Automatic Rifle. Bullets
were fed into the clip, the clip loaded into the magazine. Stripper clips
are also used to load magazines. I call magazines magazines and clips clips.
Revolvers use speed loading clips. Clips hold bullets, magazines hold
bullets in the rifle.

Unless you are talking about "newsclip" as a magazine instead of a
periodical.

No. More accurately it's described as attaining a state where some of
the water vaporizes.

Is water superheated by a microwave oven (above 100C, yet no vaporization
because of lack of nucleation) considered boiling water?

That *can* be achieved by heating, indeed this
is the most common way of doing it. But it's not the only way, and even
heating water to the boiling point is something that varies under the
relatively insignificant differences in air pressure between sea level
and a moderate mountain.

Heating is the most common method for boiling water for a number of
reasons. It's convenient, and technically less complicated than
creating a sufficient vacuum. Also, boiling water is hardly ever a
goal, it's a step in a process where higher water temperatures are
desired for other things.

Sometimes boiling is undesirable as in hot water systems. The pressure is
kept high to raise the boiling point so no vapor forms in the system.

Does frozen carbon dioxide cause water to boil when you throw it in? Is
the
carbon dioxide boiling? Is it sublimating?

Irrelevant. A totally broken analogy. Two completely different processes
that only cause a visually similar effect.

Correct. I asked these questions to test understanding of the phenomena.


So the bottom line: Boiling water is water with vapor bubbles in it? It
doesn't matter what means induced these bubbles? Does boiling water have
some unique property?

Really? Ever heard of "fire"? It's the latest technology,
great for producing heat.



And now, just to show how truly impossible it is to actually
teach you something, I will continue to demonstrate how
wrong you are about "boiling"!

What equation? So far you have insisted that whole issue can
be explained in plain English. Efforts to introduce math &
science have been rejected by you in favor of the dictionary
(and it's not even THE Scrabble Dictionary). Maybe you have
a problem with math? Anyway, I'm putting it in plain simple
English.

Energy has been added to the water. If it "came down the
mountain stream" then the Sun carried it up there. Either
way, the kettle on a mountain top is at a higher energy
state than water at atmospheric pressure at sea level.

The lower pressure means that less *additional* energy has
to be added to make it boil. But that energy has been added,
or the water would never boil

Wait a minute, let me back up a step for you. It takes a
fixed amount of energy to raise a given amount of water a
given temp, did you know that? Look up the term "specific
heat" in your dictionary.

I'm not changing the meaning of the word, I am pointing out
how it is applicable in cases where you don't think it is.



If water can be boiled at a lower temp on a mountain top,
then it can be boiled at a lower temp by a propeller, unless
your dictionary either defines a minimum possible temp or
specifically excludes propellors. Does it? What about in a
balloon far above the mountain top, that would be at a lower
pressure and thus lower temp even yet.... correct?

Now look at the another situation: ever hear of a cracking
column? It is how gasoline and diesel fuel are made. The
official name is "fractional distilling." Look it up in your
dictionary. A cracking column has heated fluid (such as
crude oil) pumped into it and then released into a lower
pressure vessel. Does it boil? You better believe it does,
if it didn't you'd be sitting in the dark instead of reading
this!



... As I argued with Gilligan, and he finally concurred


Actually, I don't think he concurred at all. I think he
preferred to retire from the discussion instead of showing
your folly.

Wrong

Water (or any fluid) can be boiled at a wide range of temps
& pressures. We agreed on this.

At low pressure, very little heat need be added. You agreed
that it takes less heat to boil water at the top of a
mountain because of the lower pressure. Now you are
insisting that there is some definite ratio of heat added to
pressure reduced or somehow it isn't "boiling."

Is that what your dictionary says? That it's only boiling if
X amount, or greater, of heat is added?
