Science particle theory

Cards (7)

  • Matter
    Anything that has a mass and volume
  • Particle theory of matter
    • Matter is made up of particles called atoms
    • Particles have large spaces between them
    • Different substances are made up of different particles
    • Particles are always moving
    • Particles at higher temperatures are moving faster than particles at lower temperatures
    • Particles are attracted to one another, the stronger the attractive force the closer the particles are to each other
  • States of matter
    • Solid
    • Liquid
    • Gas
  • Solid
    • Particles are closely packed together
    • Particles have strong attractive forces
    • Particles can only vibrate and rotate slowly
  • Liquid
    • Particles are closer together than in a gas
    • Particles have medium attractive forces
    • Particles can move around each other in a medium way
  • Gas
    • Particles are far apart from each other
    • Particles have weak attractive forces
    • Particles can move around freely and quickly
  • The particle theory can be used to describe and explain the differences between the three states of matter
