How The Electric Pressure Cooker Works. Upon receiving this heat energy, the bonds holding the water molecules together begin to break. When the internal vapor pressure equals the pressure exerted on it by the atmosphere, the water will start to boil and turn into vapor. As the pressure inside the cooker increases, the boiling point of water also rises. a pressure cooker works on a simple principle: Normally, water boils at 100°c (212°f) at sea level. you need to apply energy in the form of heat to boil water. Once again, lower pressure means lower temperature, so cooking times will be longer when using an electric model. the key scientific principle at play in pressure cooking is the direct relationship between pressure and temperature, described in the ideal gas law in thermodynamics. A sealed pot, with a lot of steam inside, builds up. Electric pressure cookers operate at lower pressure (12 psi) than their stovetop counterparts (15 psi). but the single biggest difference is this:
