Which of the following is not a physical property of iron? conductivity ability to rust color melting point

First, a physical property just identifies it's state, how it looks, color, and that stuff. Let's work on finding that.

⇔ Ability to rust wouldn't work as a physical property. That one changes the substance, making it a chemical change. So, we know that this can certainly be our answer!

The ability to rust is not a physical property of iron because rusting change the chemical composition of iron.

What is physical property?

The property of a metal that leads to the change in the size of the shape of metal but not in the chemical structure or composition of the metal.

Conductivity:

It is the property by which metals are able to pass electrons which connected to an electric current source or heat source.

Ability to rust:

Iron reacts with oxygen to form iron oxide which is known as rust. In this, the chemical composition of pure iron is changed.

Color is the physical appearance and the melting point is the temperature at which solid iron converts to liquid iron but the chemical composition does not change.

Therefore, the ability to rust is not a physical property of iron.
