The atmosphere exerts less pressure as altitude rises above sea level. Since the boiling point of all liquids decreases alongside air pressure, those who have scaled Everest have reported that water boils very quickly at the peak. The boiling point of water at any given pressure can be determined and the pressure for any altitude can be mathematically calculated. Therefore, physicists can determine the boiling point of water at the summit of Everest, since _______.
atmosphere exerts less pressure as altitude rises above sea level.
boiling point of all liquid decreases alongside air pressure.
water boils very quickly at peak.
boiling point of water can be determined and pressure for any altitude can be mathematically calculated.
conclusion- physicists can determine the boiling point of water at everest.
we need reason to back this.
A. air pressure at sea level is higher than air pressure above sea level.
but this somewhat we know or can infer, but this doesnt give reason why they why/how they can determine boiling point of water. reject.
B. air currents sometimes carry pressure from lower points in the atmosphere to higher points
not necessary for the argument here. out.
C. the exact height of the summit is known
this is the missing puzzle in equation. once we know the height, we can figure out altitude and the rest of the things. keep.
D. air pressure cannot be directly measured anywhere in the atmosphere
irrelevant. reject.
E. the boiling point of water is higher at sea level than it is above sea level.
we know this somehow from passage. reject.
