which of the following is true of iron?\na. it has the highest electrical conductivity of any metal.\nb. it can exist in many alloys, usually with a carbon base.\nc. it is highly valuable, has symbolic meaning, and widely used.\nd. it is a durable metal and is commonly used for casting.\nplease select the best answer from the choices provided\na\nb\nc\nd
Answer
Brief Explanations:
- Option a: Silver has higher electrical conductivity than iron.
- Option b: Iron - based alloys usually have carbon as an alloying element, but this is not the most characteristic or widely - known property compared to casting use.
- Option c: Gold and some other precious metals are more highly valued symbolically.
- Option d: Iron is a durable metal and is commonly used for casting due to its properties like relatively low melting point and good fluidity during casting, making it a popular choice for many industrial and manufacturing applications.
Answer:
D. It is a durable metal and is commonly used for casting.
