PV=nRT ?
… which is the reason why rising ocean temperature raises atmospheric CO2 partial pressure, not vice versa.
If you have a home carbonated water dispenser the effect is dramatic, so we chill the water before bubbling the CO2 through it.
I knew that 70 years ago.
What puzzled me back then was why the CO2 came out of solution when pored over ice.
Nope.
...you mean i have to read beyond the headline?
It’s those damned lithium batteries in the bottles.
“...you mean i have to read beyond the headline?”
Possibly. How old are you?
When I was a kid cokes came in bottles.
We would put our thumb over the top, shake and spray.
Was this study funded by a multi-million dollar government grant?
PV=nRT 8s the Ideal Gas Law.
It does not apply to solutions.
Water dissolves more gas when it is cold. Heat drives gas out.
Nope
I don’t drink alcohol.
While shaking can impart some thermal energy it isn’t going to raise the temp enough to practically measure. I wasn’t much of a soft drink drinker but I did like finding glass coke bottles in ditches and taking them into the local 7/11 for the deposit.
off to read the article...
I’m a bit rusty in the chem...
That is involved, but this is for two phase two component (H2O , CO2) system at two different temperatures. So it depends on the components esp water being polar.
“While shaking can impart some thermal energy it isn’t going to raise the temp enough to practically measure.”
True, but we knew then that warm coke sprayed more than cold.
thanks, i’ll take a look later
I do recall 104.5 degr between bonds for water...
In my considered scientific opinion, it’s because they are more sparkly.
water is non polar, correct?
