Okay thank you.
So I used E=K+U = 0.5v^2 -GM/r to find the orbital energy and I got E=-6.46E7 (joules?)
By the way, do we just assume the mass of the asteroid is negligible in the energy eqn?
So then the asteroid is in a bound orbit since the energy is negative, right?
However, how would I...
Homework Statement
Hey, I need to find whether an asteroid is in a "bound orbit" around the Sun.
Furthermore, describe the shape of the orbit (elliptical or circular).
The only information I have been given is its velocity and position at a random point.
v_o=61m/s
r_o=13.75AU=2.06E12m
I also...
Homework Statement
Define the Helmholtz free energy as F=E-TS.
Show that the internal energy E=-T2\frac{∂}{∂T}(\frac{F}{T})V
Homework Equations
S=(\frac{∂F}{∂T})V
Perhaps \beta=\frac{1}{\tau}
and \tau=kBT
The Attempt at a Solution
E = F+TS
E = F+T(\frac{∂F}{∂T})V

Oh I see.. I didn't realize μo was 0 for gas phase.
So the answer is simply
ΔE = N(Δuo) + N(Δv)kT/2 = N(0.12eV) + N(2)k(700)/2 = 17398 J/mol?
Thank you so much, that makes a lot more sense... I knew that ΔE couldn't possibly be zero lol
Thanks again!

Thanks.
Yes, it should be -1.9224x10-21 J/mol
And you're right, I should be using the other work equation...

I'll give this question another try now, because I've had some time to think about it.

The latent heat of vaporization of a substance is defined as the amount of heat required to transform the substance from its liquid into its vapor phase. A certain material has a boiling point of 700K and its molecules have three degrees of freedom in the liquid phase but...
