Question

Cast iron is a metal made from iron ore with a carbon content of_______.

1) 10-15
2) 6-9
3) 3-5
4) 2

Answer 1

Cast iron is a type of iron with a higher carbon content, typically ranging from 2-4%, but it can go up to 6% in some cases. The higher carbon content makes it brittle but also gives it specific properties that make it suitable for certain uses.

Step-by-step explanation:

Cast iron is a type of iron that contains a higher carbon content compared to other types of iron or steel. The correct answer is 1) 10-15. Cast iron typically has a carbon content ranging from 2-4%, but it can go up to 6% in some cases. The higher carbon content in cast iron makes it brittle but also gives it certain properties that make it suitable for specific uses, such as high melting point and excellent heat retention.
