  7. What is the change of state called when a solid turns into a liquid?

  8. Describe how the particles are arranged in a solid.
    • The particles in a solid:
    • are close together
    • are arranged in a regular pattern
    • are held together by strong forces called bonds
    • vibrate in a fixed position
    • cannot move from place to place
  9. Describe how the particles are arranged in a liquid.
    • The particles in a liquid are:
    • close together
    • arranged in a random way
    • they can move around each other
    • the bonds in a liquid are strong enough to keep the particles close together, but weak enough to let them move around each other..
  10. How are the particles arranged in a gas?
    • The particles in a gas are:
    • far apart
    • arranged in a random way
    • can move quickly in all directions
    • no bonds between the particles in a gas, so they are free to move in any direction.
  11. What causes pressure?
    • The movement of particles hitting the side of the container.

  12. Describe how particles are arranged in a liquid.
    Particles can move and they take the shape of the container they are in, there is some attraction between particles.
