To identify the metals [tex]$( M ), ( N ), ( O ), ( P )$[/tex] based on the given table, we'll use the properties of metals and their common applications. Let's solve it step-by-step:
1. Bicycle Handlebars:
- Parts to be coated: Bicycle handlebars
- Metal Used to Make: Iron
- Metal to be Coated: [tex]\( ( M ) \)[/tex]
Bicycle handlebars are usually coated with a corrosion-resistant metal to ensure durability and resistance to rust. A common metal used for this purpose is Chromium.
Therefore, [tex]\( ( M ) = \text{Chromium} \)[/tex].
2. Machinery Parts:
- Parts to be Coated: Machinery parts
- Metal Used to Make: [tex]\( ( N ) \)[/tex]
- Metal to be Coated: Chromium
Machinery parts need to be made of a strong and durable metal to withstand heavy usage. A frequent choice for machinery parts is Steel.
Therefore, [tex]\( ( N ) = \text{Steel} \)[/tex].
3. Ornaments:
- Parts to be Coated: Ornaments
- Metal Used to Make: Copper or its alloys
- Metal to be Coated: [tex]\( ( O ) \)[/tex]
Ornaments are often coated with a shiny and decorative metal to enhance their appearance. A popular choice for coating ornaments made of copper or its alloys is Gold.
Therefore, [tex]\( ( O ) = \text{Gold} \)[/tex].
4. Parts made of iron:
- Parts to be Coated: [tex]\( ( P ) \)[/tex]
- Metal Used to Make: Iron
- Metal to be Coated: Tin
Iron parts coated with Tin are typically used to prevent rusting. One common application is for packaging to protect food from rust, thus Food cans are often made with iron coated with Tin.
Therefore, [tex]\( ( P ) = \text{Food cans} \)[/tex].
Summarizing:
- [tex]\( ( M ) = \text{Chromium} \)[/tex]
- [tex]\( ( N ) = \text{Steel} \)[/tex]
- [tex]\( ( O ) = \text{Gold} \)[/tex]
- [tex]\( ( P ) = \text{Food cans} \)[/tex]
This completes the identification of the metals based on the given table and properties related to their use.
