EVERYDAY SCIENCE

Detailed explanation-1: -heat conductivity is the physical property that makes metal pots good for cooking.

Detailed explanation-2: -Heat moves quickly through materials such as metals because they have high heat conductivity. Cooking pots are made of metal so that the heat of the stove can move quickly through the metal to heat the food.

Detailed explanation-3: -The ability of a substance to conduct an electrical charge or heat is measured by conductivity. It is a physical property because the identity of the substance used is not changed i.e. no change in chemical composition. It just transmits the form of energy, such as electricity or heat.

Detailed explanation-4: -The two most important factors are thermal conductivity and heat capacity. Almost all discussions concerning the materials used in cookware are focused on these two factors.

Detailed explanation-5: -Good thermal conductivity, malleability, light weight and high melting point are the properties of aluminium due to which it is used for making cooking utensils.
