Answer:

84.75°C is the boiling point of water at an elevation of 7000 meter.

Explanation:

Rate of change of pressure = 19.8 mmHg/1000 ft

1 foot = \frac{1}{3.28} meter

19.8 mmHg/1000 ft=\frac{19.8}{1000}\times 3.28 mmHg/m=0.065 mmHg

Pressure change for every 1 m = 0.065 mmHg × 1= 0.065 mmHg

Elevation      Pressure

     0 m       760 mmHg

1000 m       695 mmHg

2000 m       630 mmHg

Pressure drop at the elevation of 7000 m: 7000\times 0.065 mmHg=455 mmHg

Pressure at 7000 m = 760 mmHg - 455mmHg = 305 mmHg

The boiling point of water decreases 0.05°C for every 1 mmHg drop in atmospheric pressure.

At 7000 meter elevation the boiling of water will be :

0.05^oC\times 305=15.25^oC

Boiling point of water at 7000 meter elevation :

100.0^oC-15.25^oC =84.75^oC

84.75°C is the boiling point of water at an elevation of 7000 meter.
