The boiling point of liquids at higher altitudes -
aincreases
bDecreases✓ Correct
cRemains the same
dIncreases and then Decreases
eNone of the above/More than one of the above
Explanation
When pressure increases, the boiling point of a liquid increases, and when pressure decreases, the boiling point decreases. Pressure and boiling point are directly proportional. Therefore, the boiling point decreases with altitude because atmospheric pressure decreases with height.
