[Grade11 Biology] What is the biological significance of water’s heat of vaporization?

I honestly don't get on how to answer it in a biological significance answer... can you guys help me out. My answer is in the lines of ice caps melting so by knowing that the water is 100C we could lessen the melting of ice caps. I think that answer is wrong, any help please. Thank you

@Elon Musk Yes. Also, despite high outside heat, rapid water vaporization can counter-intuitively cause it to snap freeze & block cooling channels. twitter.com/elonmusk/stat…

Looking to a surfactant that is has a similar heat of vaporization as polypropylene Glycol and is edible. Any suggestions?

Looking to mix coconut oil into my E-juice. But PG and vegetable glycol do not have high lipid solubility. So I was looking for a surfactant that i can add to help dissolve it. Any suggestions?

I am now a believer in packing half a bowl. This amount got me to 9/10 on the first hit. Previously, the first hit was usually the weakest one. (I assume because when I filled the bowl, it made the material more difficult to heat and thus reach vaporization temperatures) imgur.com/a/zvVR79b

Pilots / Aviation experts, Why don't all planes, small and large, have some sort of emergency deployable parachute system? It seems like, at least in situations of engine failure, instead of barreling toward the ground at vaporization speed, they could be slowed down to a less lethal 25-45 MPH?

Hey all, new to the community and have a question about determining vaporization of brazing alloys!

I’m in an R&D role tasked with determining by-products/safety risks associated with induction brazing with some nasty alloys. A customer wants us to use an alloy that contains cadmium, among other nasty stuff, and I’d like to set up an experiment to record/document any fumes or dust created; and if possible find some sort of info on how much heat/for how long we can sustain the process before volatility occurs. Say we braze at the lowest temperature(X) needed to make the bond, I need to determine the time(Y) we can use that setting before there’s a chance our operators are at risk of exposure. This sounds really basic to me, but is there some kind of math we can do to determine that energy limit based on application of a given heat over a given amount of time? I’m stumped and didn’t have the opportunity to take thermodynamics, thanks for any help!

Question regarding vaporization potential of 3-HO-PCE

So another lab has informed mine that any sort of vaporization of 3HOPCP results in the release of cyanide like compounds. The same lab reported that this was not the case with 3HOPCE. Can anyone else confirm this report, or have any guesses, theories? My lab will not be doing this test unless it is certain of the safety of the test, rest assured.

Why does the compression of fuel/air in an engine increase vaporization?

In a 4 stroke engine, during the compression stroke, a gasoline/air mixture is compressed inside the combustion chamber. This decrease in volume leads to an increase in pressure which in turn leads to an increase in temperature. I understand that the increased temperature leads to better fuel vaporization (for the same reason that boiling a pot of water will increase the vaporization of that water.) However, the pressure is also increasing - doesn't that work against the goal of increasing the fuel vaporization? In other words, doesn't the increased pressure work to condense the fuel out of vapor and into droplets?

Maybe both of these forces are acting on the fuel, but the temperature increase has a larger effect and "wins out" causing more vaporization to occur than the pressure increase causes condensation. How is the amount of vaporization even measured?

I've been trying to figure out exactly how a compression stroke in an engine increases the engine's efficiency. I've found many articles/posts about the effect of the increase in temperature, but nothing mentioning the condensing effects of increased pressure.

As a tangent, if I take a sealed disposable water bottle with a few droplets of water in it, and I twist it (like this) to increase the pressure inside, the temperature will increase. If I then leave the bottle untouched for a while, so that the heat dissipates and it returns to room temperature then there will be fewer water molecules in a gaseous state compared to before I twisted the bottle. Is that correct?

Vaporization instead of combustion ?

is it true that the most effective method of consumption for crack is to vaporize it instead of smoking it.

Apparently when smoking, burning causes a great loss of active cocaine freebase molecules.

The objective when vaporize is to avoid combustion and stop at the sublimation phase by rising to the temperature of 92 Β° C and not to exceed it (or much less than with a lighter)

Have you tried with an electronic cigarette or pressurized vaporizator ?

Water Enthalpy Of Vaporization

First of all, this is not a homework problem, just a question. I have seen that there are two popular enthalpy of vaporization for water: 44kj or 40.62kj. I know that the second one is the standard value ( water at 298K),but what makes they differ? I thought the difference happened because we first need to heat the water to 373K, bur using the formula Q = mcβˆ†T and Q = m*L I have got an enthalpy of 46kj. So what makes the difference? I don't want any calculation, I am looking foward to understanding what happens.

Hello. Wanted any help/suggestions as why i cant get vaporization of a-php, Hexen, or 3FMP in an oil burner

Guys,I've had really bad luck with vaping in oil burners

  1. I can get the a-php to vaporize decently if its a pure crystal
  2. The Hexen powder just sticks to the bowl and never liquidizes
  3. The same thing with 3FMP
  4. When the hexen and 3fmp don't liquidize, I just hold the lighter to them until the bowl tuns black but at least I get some smoke out of them.

I hold my flame about 1/2 from the burner with a BIC lighter and rotate it back and forth for about 30 seconds until I see see vapor (but this only happens with the a-php. What am I doing wrong or do I need to use a different kind of lighter?

I followed the instruction manuals on how to smoke meth correctly, but these tips only work for the a-php crystals.

My pipe was very dirty. Is it important to clean it after each use to get the best vaporization?

Thanks guys!

Hi, I’m a chemistry enthusiast very new to cannabis distillation. If one dissolves BHO shatter in ethanol and preforms a short path distillation does it produce a notably more potent product or would it be more adventitious to simply dilute the shatter for vaporization

Is distilling bho with ethanol β€œoverkill” for vaping or is the end product significantly more refined?

Advice for someone new to (and completely uneducated regarding) wax pens and vaporization

Hey everyone,

So I just recently purchased a yocan evolve plus xl and have been using shatter in it. While obviously not even close to ideal, I'm kinda on a tight budget and don't know anything about the customization of wax pens. What should I invest in for the most bang for my buck? I've seen that a lot of people use the yocan atomizer but other parts from other pens. How does that work? Are there any helpful articles/videos that do a good job of introducing someone like me to these devices?

Thank you so much for the help!

Stargate vaporization

In several episodes of SG-1, it’s mentioned that the gate opening will vaporize things in front of it. I also thought it did it for things behind it.

I’m watching S03 E19 β€œNew Ground” and there is a gate embedded in stone. The stone behind it is still there after they open the gate a couple of times.

Am I wrong?
