Lecture 2: Making the elements

1. Chemical composition of the solar system
   1. Making the elements
2. Condensation from the nebula
   1. Thermodynamics

We acknowledge and respect the lək̓ʷəŋən peoples on whose traditional territory the university stands and the Songhees, Esquimalt and W̱SÁNEĆ peoples whose historical relationships with the land continue to this day.

Should the Sun and Earth have the same chemistry? What about Earth and Jupiter?

Do the planets share a common origin with the Sun?

Condensation sequence

• Condensation: as a gaseous material cools, it will condense into solid or liquid form
• Some questions we will consider:
  • Starting with a hot gas with the composition of the sun/nebula, what solids condense first? (These solids are the building blocks of planets)
  • When does all of a specific element finish condensing?

• To answer these questions, will need to use thermodynamics
