Question

Define them and write two uses of each of them.In your practical copy, make a list of objects made up of metals such as iron, aluminum, silver, gold and zinc. Write any twoLIses of such metals. Why is a specific metal used for making specific object?

Answer 1

Metals such as iron, aluminum, silver, gold, and zinc have various uses in everyday objects due to their specific properties. Iron is strong and durable, aluminum is lightweight and corrosion-resistant, silver is lustrous and conductive, gold is beautiful and corrosion-resistant, and zinc protects against corrosion and has antimicrobial properties.

Step-by-step explanation:

Metals are elements that have certain properties such as being shiny, conducting electricity and heat well, and being malleable and ductile. They are widely used in various objects due to these properties.

1. Iron is commonly used to make objects such as nails, screws, and car bodies because it is strong, durable, and can withstand high temperatures.
2. Aluminum is used to make objects like beverage cans, window frames, and aircraft parts because it is lightweight, corrosion-resistant, and has good thermal conductivity.
3. Silver is used to make jewelry, coins, and mirrors due to its high luster, conductivity, and resistance to tarnishing.
4. Gold is used for jewelry, electrical connectors, and dental crowns because of its beauty, high electrical conductivity, and resistance to corrosion.
5. Zinc is used in galvanizing steel, batteries, and alloys due to its ability to protect other metals from corrosion and its antimicrobial properties.

Specific metals are used for making specific objects because each metal possesses unique properties that make it suitable for certain applications. For example, iron is used for making car bodies because it is strong and can withstand impacts, while silver is used for making mirrors because it reflects light well.
