(a) Diamonds can be made artificially by subjecting pure carbon to very high pressure and temperature. The synthetic diamonds are small whereas natural diamonds are big.
(b)(i) Diamond is hard whereas graphite is soft.
(ii) Diamond is a non-conductor of electricity whereas graphite is a good conductor of electricity. The difference in the physical properties of diamond and graphite arises because of the different arrangements of carbon atoms in them.
