Storyboard Text

  • My name is Aaron and I am a argon molecule.
  • We are so excited to see what we will change into.
  • It is getting colder the further we move away from the sun, Our kinetic energy is decreasing and our intermolecular forces are strengthening.
  • It was getting too cold, so we moved closer to the sun, increasing the temperature and our kinetic energy, but our intermolecular forces were completely pulled apart.
  • Aaron is a colorless, odorless, tasteless gas that is present in less than 1% of the Earths atmosphere. Aaron and his friends are traveling to outerspace to see if they can change their phases.
  • We are so uncomfortable being a solid that we move closer to the sun to increase the temperature and our kinetic energy. However, our intermolecular forces are weakened.
  • When we reach -189.4 degrees Celcius, we change from a gas to a liquid through a process called condensation.
  • It is soooo cold, but we are going to see how cold we can get!
  • When we reach a temperature of -185.8 degrees (our boiling point) celcius, we change from a liquid droplet to a gas through evaporation. Very quickly, we decided that was too hot, and moved just a bit further away from the sun. Our temperature and kinetic energy decreased and our intermolecular forces increased as we turned from a gas to a solid. This is called deposition and it happens between -185.8 and -199.3 degrees celsius.
  • We decide to come back to earth, because that is where we are the most comfortable. We are a noble, inert gas here.
  • We start to change from a solid back to a liquid droplet at -189.3 degrees celsius. This is called the melting point.
  • As we move away from the sun and the temperature lowers our kinetic energy decreases and our molecules slow as the intermolecular forces get stronger. When we reach -199.3 degrees celsius (our freezing point) we turn into a solid. We can't move and we don't like it at all.
  • As we travel back to Earth, the temperature rises, our molecules move faster as our kinetic energy increases. Our kinetic energy increases so much that the intermolecular forces break apart and we change from a solid back to a gas during sublimation which happens between -199.3 and -189.4 degrees celcius.
