Solids, liquids, gases - all matter - are made up of atoms (or other things, like molecules, that are made from atoms)! ELEMENTS are the kinds of atoms that we can have. Carbon is an element, hydrogen is an element, and so is oxygen.
so it is c hope this helps
Answer:
a. Aim of the experiment: To identify the magnetic fields around the bar magnet.
b. After tapping the paper, the iron filings align themselves according to the lines of the magnetic force of bar magnet. The magnetic field is more concentrated at the ends of poles as most of the iron fillings are attracted at the poles and the pattern form by iron filling shows the magnetic field of the bar magnet.
c. If iron filings will be replaced with grit, there will be no magnetic movement around bar magnet as grit is not a metal and do not have any magnetic properties.
