1a)
Diffusion is the process by which particles of a substance move from a region of higher concentration to a region of lower concentration until they are evenly distributed, due to their constant random motion.
1(b)
*PICK ANY TWO*
(I) Diffusion – e.g. the spreading of perfume smell in a room.
(ii) Brownian motion – irregular zig-zag movement of tiny particles suspended in a fluid.
(iii) Osmosis – movement of solvent molecules through a semi-permeable membrane.
(iv) Expansion of gases when heated – showing that particles are in constant motion and move farther apart.

*NUMBER TWO*
(2a)
(i) Majority carrier:
Holes
(ii) Minority carrier:
Electrons
(b)
*CHOOSE ONLY ONE*
(I) It requires no heater filament, so no heating is needed before operation.
(ii) It consumes less power.
(iii) It is smaller and more compact in size.
(iv) It has a longer lifespan and is more reliable.

A hard magnetic material is a material that is difficult to magnetize but, once magnetized, it retains its magnetism for a long time and is not easily demagnetized.
Examples: steel, cobalt steel, and Alnico.
(6b)
*PICK ANY ONE*
(I) Diffusion – e.g. perfume spreading through air.
(ii) Brownian motion – random movement of tiny particles suspended in a fluid.
(iii) Osmosis – movement of solvent particles through a semi-permeable membrane.
