presents: How does a pressure cooker work?
The laws of Physics apply to our everyday activities, even cooking food. Watch this animated video explaining how a pressure cooker works to cook our food faster.
Steam and Pressure are 2 very important things happening inside the chamber of a pressure cooker.
A pressure cooker is made up of a pot, a lid which fits precisely on the pot with a locking mechanism; a rubber ring that goes between the lid and the pot so that no air can escape; a valve on top of the lid with a release whistle
There are 2 extremely important parts in all pressure cookers. The rubber ring that goes between the pot and the lid ensures that no air escapes from inside the container; if it did then the pressure would not be able to build up.
The valve on the top is a safety measure that makes sure the pressure does not build up to dangerous levels inside the pot. This could lead to a potentially dangerous explosion. It is designed to allow some of the steam to escape after the pressure inside reaches a certain point. And with that startling whistle we know how much the food has been cooked.
