How Matter Changes State: From Ice to Steam

  1. Solid Start: Ice is water in its solid form, with molecules locked in place.
  2. Melting Magic: Heat makes molecules vibrate faster until ice melts into liquid water.
  3. Liquid Flow: In water, molecules slide past one another, giving it fluid motion.
  4. Boiling Point: At 100°C (212°F), water molecules gain enough energy to escape as gas.
  5. Steam Rising: Water vapor spreads freely, filling any container or open air.
  6. Freezing Again: Cooling removes energy, slowing molecules until water solidifies as ice.
  7. Condensation: Steam loses heat, turning back into liquid droplets on cooler surfaces.
  8. Sublimation: Sometimes ice skips liquid entirely and turns straight into vapor, like dry ice.
  9. Energy Exchange: Every state change is powered by energy being added or removed.
  10. Everyday Wonder: From boiling kettles to frosty windows, phase changes surround us daily.
