A pan is made from metal, which is a good conductor of heat, but unfortunately, this means that thermal energy is transferred to the surroundings very easily. Kettles are normally made from plastic. Plastic has a lower thermal conductivity than metal and so less energy is transferred to the surroundings. This makes a kettle more efficient than a pan for boiling water.","video":null,"image_url":"https://www.developingexperts.com/file-cdn/images/get/e89ba441-1fb0-42a3-95e0-303089013d3c?transform=resize:800x600;format:webp;quality:80"},"limitChoices":{"min":1,"max":1}}}
