Which among the following is based on the principle that boiling point decreases with decrease in atmosphere pressure?

Cooking food at sea-level takes longer period of time

Cooking food at higher altitudes takes longer period of time

Working principle of air coolers

Working of pressure cooker.

The correct Answer is:

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.
