Final answer:
Water boils at 100 degrees Celsius. The pan is made of metal because it conducts heat well. The handle is made of wood to provide a safe grip and prevent burns.
Step-by-step explanation:
The boiling point of water is 100 degrees Celsius. This means that water boils and turns into steam at a temperature of 100 degrees Celsius.
The main part of the pan is made from metal, typically aluminum or stainless steel, because these materials conduct heat well and distribute it evenly across the pan's surface. This allows for efficient heat transfer and faster heating of the water.
The handle is made of wood because wood is a poor conductor of heat. This means that the handle will not get as hot as the metal part of the pan when it is placed on a stovetop. The use of wood for the handle ensures that it remains cool to touch and provides a safe and comfortable grip.
One other material that could be used instead of wood for the handle is a heat-resistant plastic or silicone. These materials are also poor conductors of heat and can withstand high temperatures without melting or warping.
