Cooking utensils are made of metals but their handles are made of wood or plastic, Why?

Why do pots have wooden handles?Question 19AnswerA.To increase heat retentionB.To enhancing durabilityC.To enhance appearanceD.To minimize heat conduction

Identify why it is safer to stir a pot of hot food with a wooden spoon instead of a metal spoon. Select two options.Wood is a good conductor and it can quickly transfer heat away from your handMetal is a good insulator and it can easily trap heat from the hot foodMetal is a good conductor and it can quickly transfer heat to your hand and burn youWood is a good insulator and does not transfer heat quickly to your hand

Plastics have replaced wood, paper, glass, steel, and aluminum as the materials of choice for many common objects used today. They usually have interior mechanical properties such as stiffness, strength, and temperature resistance to the materials they have replaced. However, plastics succeed because of their low density, toughness, and design flexibility. Much of this design flexibility is due to the manufacturing processes that have been developed to shape them into simple and complex forms that would be costly or even impossible to produce with traditional materials.Moulding processes have been around for a long time and are particularly suited to making plastic parts. Most of the processes can efficiently produce plastic parts in high numbers, but even where low numbers are involved, the complexity of the required shape may reduce the cost of moulding a part in plastic over machining a part from metals.Plastics production really started in the mid-20th century. Today there are hundreds of different plastics available, each one developed to have specific characteristics to meet the requirements of different users. The list of plastics appears to be endless but they fall into two categories, thermoplastics and thermosets. Thermoplastics can be melted and recycled into new parts. Thermosets are stronger than thermoplastics but cannot be recycled into new parts and have to be disposed of in other ways. Because plastics are not naturally biodegradable and not all plastics can be recycled, there is a real problem in disposing of plastic waste.To help answer this concern, bioplastics are being developed from plant materials. It is possible to produce a mouldable “plastic” with ground-up natural cellulose, other materials, and water. Drug capsules are made from starch-based bioplastics.Summary:Plastics are used for many common objects because they are strong, stiff and have (1) to temperature. The design flexibility of plastic makes it easy to be shaped into simple and complex forms, which is more expensive or impossible to manufacture with other (2) . Moulding process is a suitable method for making plastic parts. The cost of moulding a part in plastic is cheaper than one in (3) . Plastics are divided into two (4) . Thermoplastics can be heated and recycled into new parts but thermosets have to be disposed of in other ways. To solve the problem of disposing of plastic waste (5), are produced from plant materials. Drug capsules are made from this material.

List the two quality characteristics of cooking utensils that are used to determine their effectiveness for cooking, what methods of cooking they are best suited for:

If polypropylene plastic is used to mass produce chopsticks, which materials, other than ivory, would have been used prior to plastic?
