Homework Statement

Define what is mean by polytrope and polystopic index n. (This is work 2 marks)

The Attempt at a Solution

A polytrope is a solution for denstity for the polytropic equation of state.


Polytropic index is defines as: y = 1 1/n


So do you think I have defined them properly? How would you do it. I only ask because this seems to come up a lot and I would rather get these somewhat easy two marks.
