Diffusion - The random mixing and intermingling through the random zig-zag motion of particles from an area of high concentration to an area of low concentration till there is equilibrium throughout.
Dissolving/Dissolution - The process that occurs when solvent molecules are colliding with crystal particles through random zig-zag motion. Due to which the solute particles enter the solvent and are surrounded by solvent particles.
Atoms - The smallest particles that we cannot break down further in chemical reactions
Molecules - 2 or more atoms joined together chemically
Ions - Atoms or groups of atoms that carry a charge


Condensation - Gas to Liquid [Lose]
Freezing - Liquid to Solid [Lose]
Boiling/Evaporation - Liquid to Gas [Gain]
Melting - Solid to Liquid [Gain]
Sublimation - Solid to Gas [Gain]
