At high pressure (deep in the earth), does water boil at a temperature higher or lower than 100 degrees C?

Question

hint—ever been camping at high altitude? What happens to the boiling point at high temperatures?

Answer 1

Higher. Pressure raises boiling point.
Thats why water increases the violence
of volcanic eruptions.
Side note:
In the deep ocean vent hot springs liquid
water temp.s as high as 800 F. have been
measured.

Answer 2

Yes, provided that the pressure is greater than 1 atmosphere, 760 torr, 760 mmHg. In a pressure cooker, people cook foods faster because the water gets hotter. However, there is a critical temperature of about 350degC above which water exists only as steam and cannot be compressed/condensed to liquid no matter what the pressure.

Answer 3

According to the ideal gas law, PV=nRT

We can assume constant volume and constant moles of the water

So we can replace nR/V by a single constant to make this easier to understand "k"

P=kT

But at higher temperatures, the pressure is lower. So say hypothetically 0.5P is the pressure at height P

To maintain equality the temperature would have to be lowered to 0.5T

So therefore, water has a lower boiling point at higher altitudes

Answer 4

Higher pressure, higher boiling point, lower pressure such as at high altitude lower boiling point.

Answer 5

the higher the presure the higher the boiling point. like ways the lower the presure the lower the boiling point. once in physics class we boiled water at room temp by putting it in a vacume chamber and removein the air presure.

Answer 6

Higher.

You can boil water in a hand held jar. If you lower the atmospheric pressure inside the jar.

Answer 7

I belive that it is a higher temp. beucase the water is not able to expand.

Answer 8

im guessing its the same for higher altitudes

boiling point and freezing point will never change

Answer 9

more pressure more temp
less pressure (in mountains) less temp
