I'm guessing this is HW, from the phrasing of the questions.

 

Does #2 help you with #1?

 

I think all of them can be Googled.

I Googled all of them but no luck. I need these question to be posted in the area of Earth Science to get the help of those that major in Geology. With these questions answered I can come up with the specific heat capacity of Earth's inner core, which would further assist my study in Seismo-electromagnetics. I am trying to make my study a public study with the collaborations of others on this forum. Any contributions would help.
