  1. 1All stuff is made of [blank_start]particles[blank_end] (molecules, ions or atoms). The [blank_start]forces[blank_end] between these particles can be weak or strong, depending on whether it's a [blank_start]solid[blank_end], [blank_start]liquid[blank_end] or a [blank_start]gas[blank_end].
    1. Aparticles
    2. Bforces
    3. Csolid
    4. Dliquid
    5. Egas
  2. 21) There are [blank_start]strong[blank_end] [blank_start]forces[blank_end] of attraction between particles, which hold them in [blank_start]fixed[blank_end] [blank_start]positions[blank_end] in a very regular [blank_start]lattice[blank_end] [blank_start]arrangement[blank_end].
    2) The particles [blank_start]don't move[blank_end] from their positions, so all solids keep a [blank_start]definite shape[blank_end] and [blank_start]volume[blank_end], and don't flow like liquids.
    3) The particles [blank_start]vibrate[blank_end] about their positions - the [blank_start]hotter[blank_end] the solid becomes, the [blank_start]more[blank_end] they vibrate (causing solids to [blank_start]expand[blank_end] slightly when heated).
    4) If you [blank_start]heat[blank_end] the solid (give the particles [blank_start]more energy[blank_end]), eventually the solid will [blank_start]melt[blank_end] and become [blank_start]liquid[blank_end].

    20. Tmore energy
    21. Uless energy
    22. Vmelt
    23. Wliquid
  3. 31) There is [blank_start]some force[blank_end] of attraction between the particles. They're [blank_start]free[blank_end] to [blank_start]move[blank_end] past each other, but they do tend to [blank_start]stick together[blank_end].
    2) Liquids [blank_start]don't[blank_end] keep a [blank_start]definite shape[blank_end] and will flow to fill the bottom of a container. But they do keep the [blank_start]same volume[blank_end].
    3) The particles are [blank_start]constantly[blank_end] moving with [blank_start]random motion[blank_end]. The [blank_start]hotter[blank_end] the liquid gets, the [blank_start]faster[blank_end] they move. This causes liquids to [blank_start]expand[blank_end] slightly when heated.
    4) If you [blank_start]cool[blank_end] a liquid, it will [blank_start]freeze[blank_end] and become [blank_start]solid[blank_end]. If you [blank_start]heat[blank_end] a liquid enough, it evaporates (or [blank_start]boils[blank_end]) and becomes a [blank_start]gas[blank_end].
    1. Asome force
    2. Bfree
    3. Cmove
    4. Dstick together
    5. Edon't

    12. Lexpand
    13. Mcool
    14. Nfreeze
    15. Osolid
    16. Pheat
    17. Qboils
    18. Rgas
  4. 41)There's next to [blank_start]no force[blank_end] of attraction between the particles - they're [blank_start]free[blank_end] to [blank_start]move[blank_end]. They travel in [blank_start]straight lines[blank_end] and only interact [blank_start]when they collide[blank_end].
    2) Gases [blank_start]don't[blank_end] keep in a definite [blank_start]shape[blank_end] or [blank_start]volume[blank_end] and will always [blank_start]fill[blank_end] any container. When particles bounce of the walls of a container, they exert a [blank_start]pressure[blank_end] on the walls.
    3) The particles move [blank_start]constantly[blank_end] with [blank_start]random motion[blank_end]. The [blank_start]hotter[blank_end] the gas gets, the [blank_start]faster[blank_end] they move. Gases either [blank_start]expand[blank_end] when heated, or their [blank_start]pressure increases[blank_end].
    4) If you [blank_start]cool[blank_end] a gas, it will [blank_start]condense[blank_end] and become a liquid.
