Q

Changes in states of matter

A
  • 3 states (solid, liquid, gas)
  • involves matter absorbing or losing thermal energy
  • completely reversible
  • the forces of attraction between particles are changing (strengthening and weakening)
  • average separation distance is changing
  • thermal expansion and contraction

Q

Thermal Expansion and Contraction

A
  • tendency of matter to change its shape, area, volume, and density in response to a change in temperature
  • not state changes
  • Matter expands when heated
  • Particles do not expand, space taken does
