Which among the following is based on the principle that boiling point decreases with decrease in atmosphere pressure?
A
Cooking food at sea-level takes longer period of time
B
Cooking food at higher altitudes takes longer period of time
C
Working principle of air coolers
D
Working of pressure cooker.
Text Solution
Verified by Experts
The correct Answer is:
B
As we move to higher altitudes, pressure decreases and hence boiling point decreases. Water boils at low temperatures on the hills and thus the cooking of food takes longer time.
