Question

For an investigation, a teacher dropped a metal bolt into a container of maple syrup and asked students to remove the bolt without touching the syrup. The students first tried to use a strong magnet to remove the bolt, but it remained on the bottom of the container. They finally poured the syrup into another container to get the bolt out. Which of these best describes the bolt’s physical properties?
A.
The bolt is magnetic and less dense than the maple syrup.

B.
The bot is non magnetic and less dense than the maple syrup.

C.
The bolt is non magnetic and more dense than the maple syrup.

D.
The bolt is magnetic and has the same density as the maple syrup.

Answer 1

Choice-C is the right one.

-- The bolt didn't react to the magnet, and just laid there.  That tells you that the bolt was made of a non-magnetic material.

-- The bolt didn't float. It went straight to the bottom.  That tells you that it's more dense than the fluid around it.
