Question

What happened if lowering the atmospheric pressure on a liquid?

Answer 1

As elevation increases, atmospheric pressure decreases because air is less dense at higher altitudes. Because theatmospheric pressure is lower, the vapourpressure of the liquid needs to be lower to reach boiling point.

Answer 2

because air is less dense at higher altitudes. Because the atmospheric pressure is lower, the vapour pressure of the liquid needs to be lower to reach boiling point.
