needed somewhere to offload this info. i needed to update anyway. where else is a better place? :]
don't bother reading all this unless you do chemistry. seriously, i wash myself of any torture you inflict on yourself by reading all this. :]btw up there is my ternary graph I leeched off the net and edited for my task. <3>: ) says:
if u increase the external pressre of a system
_∮Jes o(‧"_"‧)o sie〥 says:
oh god...
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
how does that affect the liquid?
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
like does it compress it?
_∮Jes o(‧"_"‧)o sie〥 says:
open system
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
yes
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
so say
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
u have a pot of water
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
and u take it up into the mountains
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
and u want to boil it
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
the BP will be lower
_∮Jes o(‧"_"‧)o sie〥 says:
then pressure will be less
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
yups
_∮Jes o(‧"_"‧)o sie〥 says:
and
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
but how does the lower presure affect the liquid?
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
as in does it make the vapour pressure of the liquid less to match the ecxternal pressure?
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
and so u require a lower BP for the liquid?
_∮Jes o(‧"_"‧)o sie〥 says:
i know what u mean~
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
WAIT
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
i think i get it
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
let me tell u what i think
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
and u tell me if it sounds right
_∮Jes o(‧"_"‧)o sie〥 says:
~ ~okok
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
for a system to boil the vapour pressiure of a liquid must equal the external pressure
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
in normal boiling at 1atm the temp. is increased by boiling
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
in order to raise the vapour pressure of the loiquid to match the externalk pressure
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
and so it boils
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
BUT
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
when we go up into the mountains the external pressure is much much lower
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
and so lower temperature is required to increase the vapour pressure of the liquid
_∮Jes o(‧"_"‧)o sie〥 says:
ha~ ~ might say liquid boils at external pressure, if external pressure is lower, liquid boils at a lower degree
quinɴy. [momotsuki vers.II: 8.4%] {studying, I know I am study} EMAIL SPAMWARS. >: ) says:
but i dunno how to explain that in terms of energy
_∮Jes o(‧"_"‧)o sie〥 says:
i don't know about the energy , is it that the system requires less energy to boil against the pressure
quinɴy. [momotsuki vers.II: 8.4%] {studying,} plz don't bother unless it's about study. says:
hmmm
quinɴy. [momotsuki vers.II: 8.4%] {studying,} plz don't bother unless it's about study. says:
cause i dunno how temperature changes the vapour pressure
Jessie didn't know the answer to that, so i asked adri.
quinɴy. [momotsuki vers.II: 8.4%] {studying,} plz don't bother unless it's about study. says:
how does
quinɴy. [momotsuki vers.II: 8.4%] {studying,} plz don't bother unless it's about study. says:
temperature affect vapour pressure?
Adriana says:
oh gosh
Adriana says:
pharm chem?!
Adriana says:
anything but that quyen
Adriana says:
anyways
Adriana says:
i'll just go searching
quinɴy. [momotsuki vers.II: 8.4%] {studying,} plz don't bother unless it's about study. says:
. . .
Adriana says:
mah - so temperature increases vapour pressure
Adriana says:
b/c the molecules in the substance has increased kinetic energy
Adriana says:
so when they hit the surface
Adriana says:
they have a higher likelihood of getting out
Adriana says:
u kno how molecules move around randomly
Adriana says:
some hit the surface
Adriana says:
and if the kinetic energy is high enuf
Adriana says:
it'll get out
Adriana says:
increase of temp = increase of kinetic energ
Adriana says:
ie. they move faster - more energy
quinɴy. [momotsuki vers.II: 8.4%] {studying,} plz don't bother unless it's about study. says:
keep going
Adriana says:
vapour pressure btw is the stuff on top of the substance
quinɴy. [momotsuki vers.II: 8.4%] {studying,} plz don't bother unless it's about study. says:
how does that change VP
quinɴy. [momotsuki vers.II: 8.4%] {studying,} plz don't bother unless it's about study. says:
. . .
Adriana says:
if more stuff get out of the substance ito the vapour above
Adriana says:
then that increases the pressure of the vapour
quinɴy. [momotsuki vers.II: 8.4%] {studying,} plz don't bother unless it's about study. says:
OMG
quinɴy. [momotsuki vers.II: 8.4%] {studying,} plz don't bother unless it's about study. says:
YOu'RE RIGHT
quinɴy. [momotsuki vers.II: 8.4%] {studying,} plz don't bother unless it's about study. says:
<3>_<
quinɴy. [momotsuki vers.II: 8.4%] {studying,} plz don't bother unless it's about study. says:
cause it sounds right
Adriana says:
oh ok
Adriana says:
haha
Adriana says:
cool then
sweet. thanks guys :]
much love.
