Working of pressure cooker
Pressure cooker is very essential in our day to day life. Working of pressure cooker based on converting water into steam and cooking food in steam.
Before putting food items to be cooked in pressure cooker , we put some amount of water. This water on heating, will get convert into steam.
We have a weight on the top of cooker. It covers the path through which steam will go out. But as the pressure of steam inside cooker is more, the steam will try to pass out . The only path it has to lift the weight and make itself free to go outside.
In the process of lifting the weight it makes noise through the hole. It will pass out and as the pressure decreases inside , weight will come to its original position.
When again the pressure of steam builds up inside, steam will again find its way to pass out by lifting the weight. In this process, food items kept inside the cooker will get cooked up.
But as we switch off the gas and uncover cooker , there will be water inside. In the beginning what we put water will surely get converts into steam. But when steam gets cooler it will come back to its original form, water. Thus we find water inside cooker after the work done.
