A simple temperature model for the solar nebula disk is
Tdisk(a) = 20 × SQRT 100 AU/ a K, (1) where a should be expressed in AU in this equation.
(a) Find the temperature in the solar nebula disk at the orbit of Mer- cury, Earth and Jupiter.
(b) Where is the water ice line located in this disk? [Use the conden- sation sequence values provided in the textbook]
(c) Mercury is mostly made of metal, the Earth mostly made of rock and Jupiter mostly made of gas. Are these three planetary bulk compositions consistent with the condensation sequence, if one follows the above temperature model for the Solar nebula?
