Melting : process of adding heat to a solid, causing its form to become a liquid
· Scraps of iron (Fe) bars melted to be reformed into solid iron blocks
Evaporation : process of adding heat to a liquid, causing its loose molecular bonds to break further, turning into a gas
· Saltwater (NaCl (aq)) is made to evaporate in a saltwater flat to extract salt (NaCl (aq Δ NaCl + H2O ↑)
Ionization : process of adding heat to a gas, adding energy to it, charging the molecules into ions (plasma is made up of ions)
· Energy is added in a glass tube filled with Neon (Ne), making the Neon gas to glow due to
the ionization process
Recombination : process of removing heat in a plasma, returning the ions to a ground state, becoming a gas. Sometimes called deionization.
· Neon plasma deionizes back to its gaseous form once it begins to cool
Condensation : process of transferring energy in gas molecules to the surrounding area, forcing the gas molecules to form bonds and coalesce into a liquid
· Water vapor condenses back to liquid water to form clouds
Freezing : process of transferring heat in liquids to the surrounding area, forcing the molecules to reform and bond into a solid
· Liquid Mercury (Hg), poured into a mold, is solidified when poured with liquid nitrogen (N 2 (aq))
1. Sublimation : process of adding energy to a solid, dissipating into a gas without transitioning to the liquid phase
Deposition : process of transferring energy from the gas molecules to the surrounding area, forcing them to combine and make “deposits” of clumped gas molecules together, reforming into a solid
· Water vapor (H2 O ↑) deposits itself as ice crystals (H2 O) when forming snowflakes
