Answer to Question #38800 in Electric Circuits for ayesha khan

Question

why the cooking utensils made of matels

Answer 1

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.
