A saucepan is a great metal tool for cooking food with gas or electricity. The kitchen usually consists of a grill, an oven and a few gas or electric stoves. An electric cooker is an electric cooking device for heating and cooking food. The electric cooker often has four burners and one or two ovens. There will be knobs to adjust the temperature of ovens and stoves. Unlike gas stoves, they are electric. When the automatic rice cooker is turned on, the radiator begins to heat the bowl, which provides heat to the water and the rice. Because this mixture consists mostly of water at this point, it is heated until it begins to boil. Once it begins to boil, the heat is removed by the steam rising from the pot.
