A study about free radicals in ecigs, I hope Dr. F gives some guidance

[bigdancehawk]

Technically vapor is the visible evaporation or condensation of a liquid caused by an external automotive
force such as heat,vibration or wind. Please note certain atmospheric conditions can produce vapor.
ie,,,.fog. Typically vaporization occurs before the boiling point of any liquid as most gas is invisible
unless it has properties to give it color. vapor reforms as the gas falls below its boiling point.

I'm sorry, but clouds and fog are aerosols produced when water vapor, which is not visible, condenses and forms tiny, visible droplets. LINK LINK LINK LINK

Visible vapor is caused mainly by external force. Water content in ambient air though
invisible in generally referred to as humidity. When it comes to vaping our vapor
is not caused by weather conditions but external force. Heat applied to the
e-juice causes the water in the mix to vaporize starting at about 184 degrees F.

<sigh> In common, everyday parlance, a cloud-like suspension of small liquid particles is sometime called a "vapor." I haven't disputed that and that's the term I use myself to describe what I inhale and blow out when vaping. However, the previous poster asked for an explanation of why the term "aerosol" was used instead of vapor. In science, vapor and aerosol are not the same. Thus, the term "evaporate" refers to a process whereby a liquid transforms to a gaseous state consisting of individual molecules too small for the unaided human eye to see. In scientific terms, that's a vapor. The links I've provided make that clear. With a reduction in temperature, visible droplets form when there is no longer sufficient heat to keep the molecules moving fast enough to stay separated from one another and instead they start sticking together.

We are talking about water not weather. Specifically when heated. When water
is heated the visible evaporation we see before the water boils is vapor. When
the water reaches the boiling point it turns to steam the gaseous state of
water. Steam is invisible. When the water temperature drops below
the boiling point it condenses back to vapor which is visible until it's
dispersed to the point it's no longer anything but relative humidity.
More precisely when spread to thin just a component of the air
measured in ppm. If it's not steam or visible vapor it's just
another component in the air. It's to thinned out to be considered
vapor.

Steam is invisible.

My teapot might beg to differ.

Technically he's right. Water in gaseous form is invisible. When it cools a bit it goes back into liquid form suspended as a cloud, which of course is visible.

 

[skoony]

Steam is a invisible gas. You are observing the water condensing back into
it's vaporous state.

I need to put a fireproof label on my teapot to remind myself which is what.

"The levels of radicals that we're seeing are more than what you might get from a heavily air-polluted area but less than what you might find in cigarette smoke," Richie said. The radicals are produced when the device's heating coil heats the nicotine solution to very high temperatures.

... heats the nicotine solution to very high temperatures... hmmmm

Would be interesting to see the charts as the temperatures were raised in that "study." Sounds suspiciously like another crank-it-up until everything is charred fiasco... a la the poorly done "formaldehyde" debacle.

No. It was not the case.

No. You are again wrong (we discussed it, arent' we?)

 

[Alien Traveler]

Maybe the link should be broken. Even though it's good news, it's deceptively spun to be bad.

Do not be afraid links. This one is a good one. Breaking links is a childish behavior (I do not like a toy, I brake a toy)

 

[Alien Traveler]

True, but fortunately we have guys like Bill G and others as well as our science guys who do respond, because inevitably all the bad stuff will be recycled and then we have a response.

Is it the same Bill G who makes everything partisan blaming "Obama administration"? I'd better be without such "defenders"

I blame everything on the Obama administration - Bill only blames the deeming What are you drinking tonight?

For variety I was drinking red wines. However, mixing drinks or politics and vaping is usually not a good idea.

Steam Water can occur in three states: solid (ice), liquid, or gas (vapor).
Technically water vapor is invisible also. So what are we observing before water boils?
Water above boiling temperature is gas and is invisible. Even dictionaries give contradicting
definitions of what steam and or vapor is. I tend to stick with terms more applicable to
physics when describing this process.
What we see before water reaches its boiling point is the visible evaporation of water.
Commonly called vapor. In physics this is described as a fourth state of water. Not
liquid but,not gas. This process is important to under stand because it is why we use
heating coils instead of ultrasonic vibrators,pump sprayers or,compressed gas in our
e-cigarettes. If we were discussing how clouds were made the word vapor seems to
be interchangeable depending on the subject at hand. If fog,or clouds are discussed
they are referred to as vapor. If the the amount of water in the atmosphere is discussed
that's also referred to as vapor although its more correctly referred to as relative humidity.
Here on these forums we are more concerned with what happens when we heat water not,
how clouds are formed.

Edit: there are some words that have to be taken in context of the subject at hand.

Boudreaux? Cabernet? Italian? Spanish? Not merlot I hope....

In physics the forth state of matter is called plasma.Good luck.

Cabernet sauvignon, Mendoza. Thanks for not suspecting me in drinking merlot.

It's a while back but I've had the Don Melchor from the same winery. Very good. I'll look for the Mendoza. There's only one merlot that I'd buy today - St. Francis Reserve that drinks like a Cab. Beringer's Reserve isn't bad. Duckhorn - ok, but that's about it.
