At what altitude will water boil without heat?
Correct answer: 128,000 ft.

Can we pls put metric in brackets at least? 7.2 billion people on this planet use it instead of imperial.

Ty814, it's not whining - it's quite a reasonable request. I second it. We do not say they should not use the imperial system, only that measures should be given in both

AmicableStarfish6000
UK uses both!

Below -100F (-73C) water is solid or a gas. Going from ice directly to vapor is called sublimation.

JMRACING14, it’s whatever you were taught in school. I was taught imperial and then my last few years of school, Canada switched to metric. I still prefer imperial

Now I am confused.
I thought that the lowest possible temperature was -273F or 0 Kelvin .
Absolute Zero.
How can -300F exist?

England invented the Imperial system.

Player #414252, it doesn't matter to me because I'm not going up the nearest mountain to test it out.

kat
Player #25874027, absolute zero is -273°C, not F

Lizzibef123, We use and understand both in Britain.

Coo
Lizzibef123, I think you will find that it's the British, not the English who formalised imperial measurements.

JayJay
can we have centigrade measurements included? Thanks

Geordie4Life
Player #25874027, it’s -273 Celsius not Fahrenheit

I wouldn't bet against water boiling at 100,000 feet, in the sun, since the boiling point at that altitude would be about 9F, -12C, 261K. Well, sublimating....

Player #25874027,
Absolute Zero is at about -273C ie Zero Kelvin.

This is why there are pressure cookers.

AmicableStarfish6000, Imperial is base though. Ireland has metric as base. It will be a generation before Imp is gone as anyone over 40 grew up with it.

Metalthorn
metric please?!

Player #62752956
kat, absolute zero is about -460 F.

Livoo
Player #414252, especially when it is about science. Science uses SI, which is metric

Player #30725310
Player #25874027, -273.16 C not F

Davy, Livingston, it was awful for older people they couldn't get it, we were lucky we'd been in Germany with the RAF so understood it. you do realise we were conned rotton by shopkeepers who would spend 10 bob on a loaf but 50p sounds ok, it was the same with an awful lot of things xx

Mussemouse
ft? imperial measures are not used worldwide.

sonnybud
never knew it 😁

Ferdz
That’s 39,014.4 meters

Player #22432981
SOOTI, planes are pressurized.

Alexander Supertramp
Player #25874027, thats -273 C for absolute zero

tanker2933
rosannecarlile, Why ? The US is the only backward country to still use it.

Player #3532789
Player #414252, Wouldn't have made any difference to me!

TestyAlien3443
Actually I should have said it is only solid. Comets keep their ice for centuries.

Player #1218263
Lizzibef123, yes, so ? Great Britain has used metric since 1971. About time we learn metrification .

man so much idiocy. Google the conversion if you can figure it out ffs
