Boiling Points Of Liquids?

[TheFriendlyAnarchist]

I already started this thread in the Lounge before I discovered there was a Science forum! Here's the link:
http://www.democraticunderground.com/discuss/duboard.php?az=view_all&address=105x4604786

The question was if anyone knew of any liquids that had a lower boiling point then water, and if so, where one could find pure or concentrated sources of it? (Like finger nail polish removal having a high amount of acetone in it)

Thx.

1. here's few

Ethanol (see your liquor cabinet or the hardwarestore)
Toluene (lacquer thinner at the hardware store)
Acetone (see the harware store

20. Not toluene. Try benzene, or ether. n/t

2. Lots of liquids have boiling points lower than water

Look at liquid nitrogen (-195.8 degrees C).

9. Thank you for C temperature vs. F

The stupid thing about freezing in Fahrenheit it based on salt water.
I would like to see one based on one element vs a combination of two as in C or 4 elements as in F
kalvin anyone?

[Canuckistanian]

17. Well, I'm Canadian

I think this whole Fahrenheit/Miles/Pound thing is absurd!

Oh, and I didn't know about this Fahrenheit freezing point thing.

Thanks!

19. Well...

I find Farenheit is more intuitive and has more flexibility in my mind than Celsius.

I would agree meters makes sense more than miles since a based on 10 system for distance is easier to work with.

Pounds versus kilograms? Dont work with weight much so no idea which one is better, but would guess kilograms again on a based on 10 system.

11. Water has a lower boiling point than water

at high altitude. Water at my house in NM boils at about 200, instead of 212.

Most elements have liquid, solid, and gaseous states. What is gaseous at earth surface temperature and atmospheric pressure is above its boiling point.

13. I lived at 9,000 feet and the boiling temperture is not totlaly

a relationship to heat of the boiling temperature. At 9,000 feet you better learn to cook differently when your are in a different
pressure and altitude
Taters can be boiled to cook with rabbits but it takes a little longer in the mountains.

3. What evaporates at room temperature faster than water?

5. democratic votes in a computer voting machine?

6. methanol

[acmejack]

7. ether

[Massacure]

16. Ether is a class of chemicals.

Any chemical that has two hydrocarbons bonded to each other via oxygen is an ether.

[Henny Penny]

21. Ether is perfectly aceptable shorthand for diethyl ether. n/t

8. Let's rephrase; Something thats

More or less easy to come by, and has a boling point of over 40 degrees C and less that 100 degrees C. I'm heating something, but with the means im heating it, I can only heat a small amount of water over a period of time, and I want to be able to heat a larger amount in a shorter time. Thx for the replies so far

10. You know, there are easier ways to make crystal meth

(I'm just guessing)

12. lol, very funny. Read the link if you wanna know what I'm trying to do

[Orsino]

22. You weren't very specific about the conditions, but...

...a flask of water attached to a vacuum pump will boil at room temperature. And faster if you cup it in your hand.

[IChing]

14. Damn, you beat to it with that Drano joke

LOL
what is Kalvin and why is it used in science vs Celsius?
Propane is use in a liquid state that passes from liquid to gas without going through a boiling state.





what school is this guy going to?

18. Kelvin is used because it's Zero is Absolute Zero.

The point where no molecular motion can occur.

It's just a common reference point for people who use vast scales of temperature.

15. Ask at your hardware store for cleaning solvents

denatured alcohol (ethanol) (bp about 78 C)
acetone (bp about 47 C)
toluene (bp about 60 C (I think))

or use vodka (ethanol and water, bp rises as ethanol boils off)
or rubbing alcohol (isopropanol and water, bp about 82 C; again, bp rises as alcohol boils off)
or nail polish remover with acetone (acetone, water and perfume).

Every one of these organic compounds is TOXIC, including ethanol, and is HIGHLY FLAMMABLE. Make sure that you can capture the vapors and route them away. A condensor tube under a slight negative pressure and jacketed with cold water, followed by carbon filtration, might do the job. (You could also capture the fumes under vacuum and bubble them through water to remove the organics. The bubbler would go between your fume collector and your source of negative pressure.)

On edit: I see that someone recommended Everclean. That will do the job, if you can find it.
