Q.

The boiling point of water decreases at higher altitudes is due to –

A. low temperature
B. low atmospheric pressure
C. high temperature
D. high atmospheric pressure
Answer» B. low atmospheric pressure
Explanation: At higher altitudes, the air pressure is decreased, which forces water's boiling point to lower. The air pressure decreases with altitude because of the decrease in the density of air. The lowered boiling point of water requires an increase in cooking times or temperature.
