A boy likes "magnet fish" to help remove junk from local rivers and lakes. He attaches a strong magnet to a wire and a pole examines it with no equipment. He writes down all the data he can find. What list of properties is possible for the object he caught?

Question

color, insoluble, magnetic, solid
liquids, magnetic, reflective, freezing point
state, hardness, mass, size
hardness, soluble, color, boiling point

Answer 1

The most relevant and possible list of properties for the object he caught, given that he is using a magnet to catch it, would be:

color, insoluble, magnetic, solid.

This list includes properties that would likely apply to most ferromagnetic materials (like metal) that a strong magnet can attract. Here's why:

• Color: Visual property useful for describing the caught object.
• Insoluble: Many metals are insoluble in water, indicating they do not dissolve.
• Magnetic: Since he is using a magnet, this property is essential to identify whether the object can be attracted by his magnet.
• Solid: Most objects one would catch with a magnet (like metal) are solid rather than liquid or gas.

The other lists include properties that may not be applicable or relevant to the context of catching junk with a magnet.
