Answer to Question #38800 in Electric Circuits for ayesha khan
why the cooking utensils made of matels
Cooking utensils are made out of metal because metal is an excellent heat conductor. Metal also can withstand a lot higher temperatures then other materials, and doesn't burn. In bygone days cooking vessels which sat over a flame were made of iron, steel or tin. Vessels which could go into the oven were usually made of glazed earthenware. Later there were enameled metal pans; then along came aluminium. Richer people could afford pans made of copper, a better conductor than iron or steel or aluminium. Of course this modern age has brought along modern materials; some benefiting from the materials need for space explorations.
