Why is it advisable to use pressure cooker at higher altitudes for cooking food?
It is advisable to use pressure cooker at higher altitudes for cooking food because:
i. A liquid boils only when its vapour pressure is equal to the atmospheric pressure.
ii. At high altitudes, the atmospheric pressure is very low.
iii. This causes the water to boil at a lower temperature which will take a lot of time for food to be cooked.
iv. A pressure cooker stops the boiling of water at lower temperature.
v. As a result, food cooks quickly.
