Absent freezing or boiling water will expand / contract by less than 1% at the sort of tempartures changes one is normally likley to find going up and down troodos while air volume for a given mass will (unrestricted ) change by a factor of 1.24.

In a reasonably flexible bottle say half full of water therefore the change in temperture will not cause any significant change in the volume of water and will not contribute signifantly to deformation but relative changes in air pressure acting on the non lquid part (and liquids cannot be compressed) will.

As for the experiment suggested by GR - here is one GR did earlier.

And what is altitude directly proportional to young Cobbet? :lol:

The higher up you go the colder it gets ya? :lol:

Seriously.... you guys need to go back to primary school! :lol:


Cause and Effect... there are less particles with increasing altitude hence lower air or particle density, which is the cause which causes the effect of a lower temperature, cause and effect.

Any chance of getting GIG to join you in the freezer experiment...???

It shouldn’t be too long before she joins us and answers you question… :lol:

Nobody said anything about water being in that bottle... you seem to have changed the experiment altogether! :roll:

You have claimed to have been a mountaineer in the past and even produced a picture of you posing with sherpas or something like that… so why don’t you tell us what happened to your plastic (empty) bottles as you ascended higher and higher?

My guess is nothing because you ascended very gradually giving plenty of time for the contents in the bottle to adjust to the new temperature and pressure also.

FACT: The bottles do bloat when I drive from Nicosia to Troodos. :wink:

Oh Gawd... now you've contributed Stud, we'll soon have Kimon along to tell us about some alleged Ancient Greek contribution to the field... :(
