ok heres the question:
whats the boiling point of water in deathvalley,claifornia && in denver, colorado? Are they different or the same?? if different then why??
plz help!!!!!

I don't know exactly, but they are different, with death valley higher and Denver lower. This is because death valley, with lower elevation, has more air pressure on the water molecules attempting to escape into the atmosphere. Thus more energy, that is, heat, must be put into them to make them evaporate. Te reverse is true at higher elevations, where air pressure is lower.

no the boiling points are different
the reason is the air pressure. death valley has a much lower elevation than denver colorado (the mile high city). with less pressure, it take less energy to make a substance (like water) to boil. however, with a much higher air pressure (such as in death valley) the ammount of energy required to boil the water is greater because of that added pressure, henceforth the temperature of boiling will be greater.
now the differences in these temperatures are tiny, but present
im not exactly sure of the boiling point at those places, i think that denve's BP is around 200, but the boiling point at sea level is 212 degrees.
fast fact: because of this property, ur blood will actually boil if ur in a complete vacuum

I think it has to do with pressure. I know the boiling point of water rises when water is under pressure. Thats why radiators in vehicals run at a higher temp than boiling. Its under pressure. using the same theory with altitude, Death valley is below sea level and denver is considerably higher. This should change the barametric pressures. death valley should have a higher boiling point than Denver. I wish I could tell that I am confident in this answer but I am only guessing.

Water boils at a lower temperature when the air pressure is lower. Since Denver is at a higher altitude than Death Valley the air pressure is lower and water boils at a lower temperature.

"At higher elevations, where the atmospheric pressure is much lower, the boiling point is also lower. The boiling point increases with increased ambient pressure up to the critical point, where the gas and liquid properties become identical."

They are different because the air pressure over the water is dependent on altitude, which is different in these two places.

i dont no anything abt those two places but i think the boiling point of water is the same everywhere given that you are using pure water

I would think the same.
water boils at 100 degrees celcius... period!
May take less time to get there if it's hot.... and longer if it's cold.... but when it gets there it boils.
okay... I just read the other answers....sounds like they know what they're talking about....... I don't know... but I still like my answer... short, naive....maybe.... but it makes sense to me.
