When a liquid sample is taken from sea level to a higher elevation, what happens to the external (atmospheric)pressure on the liquid and the boiling point of the liquid?
A)both decrease
B)both increase
C)pressure goes down, but boiling point goes up
D)pressure goes up, but boiling point goes down

At higher elevations, atmospheric pressure decreases because there is less air above pushing down. Consequently, the boiling point of a liquid also decreases because it requires less energy (heat) to overcome the atmospheric pressure and change from a liquid to a gas.
