At which of the following elevations relative to sea level will the boiling point of water be the greatest?
boiling point is when water becomes the same pressure as the atmosphere. Since there is less pressure the more elevated you are (because there is less atmosphere pushing down on you) water boils easier at the highest elevations.
but the low temperatures at higher levels will restrict the molecules from gaining higher kinetic energies
True, which is more relevant, low pressure or low temperature?
well, according to me both are relevant
So how do we answer the question?
lol,the best wuld be low preassures with high temperatures :)
hey wait a second we can take the water to a region of higher elevations with much hotter air currents.
hey, i guess the question implies where does the water need to be provided maximum energy (heat) which would be at higher pressures. so, (considering that the 'following' which the question refers to is not given) whichever option has the least elevation would have the highest boiling point.
Boiling point decreases as the pressure decreases. so highest boiling point will be at the sea level. As far as decrease in temperature with elevation is concerned, the fall of pressure with elevation predominates over the fall of temperature with elevation.
If you want higher temperatures, just start a fire..
This chart shows the conditions under which water is a gas: http://upload.wikimedia.org/wikipedia/commons/thumb/0/08/Phase_diagram_of_water.svg/700px-Phase_diagram_of_water.svg.png Thus, by finding what point on the chart corresponds to a certain place on Earth, you can find how close water gets to boiling there.
awesome chart.
nice
