When boiling water in a pot with no lid, no matter how much you heat it, the temper-ature will never go over 100 °C because of evapo-ration. Also the vaporised steam is at … Pressure cookers are a convenient kitchen appliance used to cook food quickly with the power of steam pressure. Even without pressure steam conducts heat and cooks faster than dry air, but with increased pressure, the steam can rise above its usual maximum temperature and cook even faster. See more The first pressure cooker was designed by Denis Papin, a French physicist. He called this cooker the "steam digester" and presented the invention to the Royal Society of London in … See more Boiling and steaming are already great cooking methods because water is a much better conductor of heat than air. To demonstrate this, think about how you can easily place your hand in a 200 F oven without it burning, but … See more The only way to increase the temperature of boiling water as it converts to steam is to increase the surrounding pressure. This can be achieved by trapping the steam in an enclosed space. … See more Water boils at 212 F, at which point it turns into steam.
