Look at the Description below: Then answer the question.
* Salt lake City, Utah is 4330 ft. above sea level. Anderson, South Carolina is 722 ft. above sea level.
* Water boils at sea level at 100 degrees Celsius. The boiling point of water decreases about 5 degrees Celsius for every mile above sea level.
* At about what temperature does water boil in Anderson, South Carolina? In Salt Lake City, Utah? (Hint: 1 mile = 5280 ft.)
Please Help!!
Thank You!
im in pre algebra 7th grade and we have this for hw
Is either of those cities over 1 mile above sea level?
5280 / 5 = 1056
For each 1056 feet the temperature decreases about 1 degree
Anderson is less than 1056 feet about sea level. At what temperature do you think water boils there?
What temperature for Salt Lake City?
no, i don't think so, since 1 mile equals 5280 ft. Utah is 4330 ft. and South Carolina is 722 ft. above sea level. They are both less than a mile.
Right they are less than a mile. But SLC is more than 1056 miles high, so water boils at a lower temperature there than 100 C. About what temperature does water boil in SLC?
If both those cities have altitudes UNDER a mile above sea level, then at what temperature does water boil?
Can you explain more on how you find the answer?
Thanks! :)

Salt lake City, Utah is 4330 ft. above sea level. Anderson, South Carolina is 722 ft. above sea level.
Are they more than a mile above sea level? If they are, apply the formula. If they aren't, then water boils at 100 degrees C.
they are less than a mile above sea level....so the water boils at 100 degrees Celsius, right?
right
I respectfully disagree.
Water's boiling point decreases 5 degrees Celsius for each mile above sea level.
Therefore, water's boiling point decreases about 1 degree for each 1/5 of a mile. 1/5 mile = 1,056 feet.
Salt Lake city is 4,330 feet above sea level.
4,220 / 5,280 = 0.82 = about 4/5 of a mile
Since Salt Lake City is about 4/5 of a mile above sea level, would water boil at 4 degrees less than 100? That would make SLC's boiling point about 96 degrees C.
i don't know.........HELP!!
5280/5280=5/5280
772=5/5280 x 772
MsSue is right, the bp is reduced as one goes upward. The ratio is 5C decrease per mile, or 5C/5280ft or 1C/1056ft
The bp is actually dependent on pressure, which can change even on mountain tops, so the rule above is an average.
i hate all of you
Omfg thnx i was stuck on this problem 2. (:
I read this and really hope these are 5th grade kids. If any older, we have a huge national problem with education which now seems to be multi-generational.
oh no Vitaliy, this person is in 7th grade pre-agebra or 8th grade pre-algebra.
i got 96 degrees celcius for the SALT LAKE CITY one
If the boiling point of water decreases 5 degrees C per mile of altitude than 100 - (4330/5280)*5 = 95.999 degrees in salt lake city. It's not an integer function.
what dose sea level mean in math :()!
The defining of reproducable physical measurments was made in a way that allowed scientests to validate each others findings. The boling point of pure water at 1 atmosphere of pressure is by definition 100 degrees C. For every day common use 1 standard atmosphere of pressure is that pressure that air exerts at the average sea level. The freezing point of pure water at a 1 atmosphere pressure is 0 C. Knowing those two points on a thermometer lets you accurately calibrate the it.
Now tell me how the calibration points were chosen for the F scale.
Go to WolframAlpha and type in "Boiling point of water in Salt Lake City"
BAM!

* Salt lake City, Utah is 4330 ft. above sea level. Anderson, South Carolina is 722 ft. above sea level.
If one mile is 5,280 feet, how many miles ABOVE sea level is each of these cities?
* Water boils at sea level at 100 degrees Celsius. The boiling point of water decreases about 5 degrees Celsius for every mile above sea level.
In New Mexico, Albuquerque's altitude is right about 5,280 feet above sea level; Santa Fe's altitude is about 7,000 feet above sea level. Since both of these cities are a mile or more above sea level, the rate of decrease applies. Now tell me about the altitudes of Salt Lake City and Anderson.
* At about what temperature does water boil in Anderson, South Carolina? In Salt Lake City, Utah? (Hint: 1 mile = 5280 ft.)
What do you think?
