The main reason why vegetables take longer to cook in boiling water at high altitudes is because
A) water boils at a higher temperature with higher altitude.
B) the temperature of the boiling water decreases with increasing altitude.
C) there is less oxygen in the air at high altitude.
D) saturation vapor pressure decreases with increasing altitude.

Question

Quizplus · Accepted Answer

As altitude increases, atmospheric pressure decreases. This leads to a decrease in boiling point temperature of water. So, water boils at a lower temperature at high altitudes which means that the temperature of boiling water decreases with increasing altitude. As a result, vegetables take longer to cook in boiling water at high altitudes.
