Water boils at a lower tempature at high altitudes, because

A

The temperature is low

B

The atmospheric pressure is low

C

The temperature is high

D

The atmospheric pressure is high

Text Solution

Verified by Experts

The correct Answer is:
The atmospheric pressure is low
The boiling point becomes progressively lower altitudes due to lower air (barometric) pressure , It decreses by `1^(@)F` for every 540 of altitude . Thus , boiling point of water at high altitude is low because atmospheric pressure is low .
