Question

Explain why food is cooked faster in a pressure cooker?

Answer 1

A pressure cooker is a sealed pot with a valve that controls the steam pressure inside, and as the pot heats, the liquid inside forms steam that raises the pressure in the pot. ​
We know that the boiling point of water decreases with a decrease in pressure and increases with an increase in pressure. ​Food cooks faster in a pressure cooker. Its because the pressure increases inside the cooker, which also increases the boiling point of water. ​So, more heat is required to reach the boiling point and is sufficient to cook food in a reduced time.
