- Iron is a kind of solid
- Iron nails are made of iron
- Hence, iron nails are solid

- Iron nails are solid
- State of matter is a property of substance includes values of solid / liquid / gas
- Therefore, iron nails are solid in state of matter

- Iron is a kind of metal
- Iron nails are made of iron
- So, iron nails are made of metal

- Iron nails are made of metal
- A thermal energy conductor conducts heat
- Metal is a thermal energy conductor
- Therefore, iron nails can conduct heat

- Iron is always magnetic
- Iron nails are made of iron
- Hence, iron nails are magnetic

- Iron nails are solid in state of matter
- Iron nails can conduct heat
- Iron nails are magnetic
- So, iron nails can conduct heat and are magnetic and are solid

Therefore, iron nails can conduct heat and are magnetic and are solid
