Solving for degeneracy electron cloud temperature

Click For Summary
SUMMARY

The discussion focuses on calculating the maximum temperature (T_Max) for a degeneracy electron cloud using the ideal gas law and the equation of state for a real gas. The ideal gas law is expressed as P*V = n*R*T, while the real gas equation incorporates an empirical constant 'a' as PV = nRT + a(n²/V²). To find T_Max, users must rearrange the real gas equation to T = (PV - a(n²/V²))/(nR) and substitute known values for pressure (P), volume (V), number of moles (n), and the universal gas constant (R). This method allows for a direct comparison of the calculated temperature to the expected T_Max.

PREREQUISITES
  • Understanding of the ideal gas law (P*V = n*R*T)
  • Familiarity with the equation of state for real gases (PV = nRT + a(n²/V²))

Homework Statement
Assume degeneracy starts to dominate approximately when the pressure expected from a completely degenerate electron gas equals that expected from an ideal gas (P_rel_e=P_ideal=1/2Ptotal) Show that the temperature at that point, which we assume will be the maximum reached, is given by T_max is true
Relevant Equations
Tmax= 7.7x10^7 K mu*mu_e^5/3*(M/M_solar)^5/3
P_rel_e = K(ro/mu_e*m_h)^5/3
P_ideal = nKT
When I try P_rel_e = P_ideal I couldn't get a single number that is close to the given T_Max. It might be that I used the wrong equations but I am not sure. Can anyone give me some guidence on this question?

To solve this question, you will need to use the ideal gas law equation and the equation of state for a real gas. The ideal gas law equation is P*V = n*R*T, where P is the pressure, V is the volume, n is the number of moles, R is the universal gas constant, and T is the temperature. The equation of state for a real gas is PV = nRT + a(n2/V2), where a is an empirical constant that depends on the type of gas.To find the maximum temperature with a given pressure, you will need to solve the equation of state for the temperature. First, rearrange the equation of state to solve for T:T = (PV - a(n2/V2))/(nR)Then, substitute the known values of P, V, n, and R into the equation to solve for T. You can then compare the calculated maximum temperature to the given value to see if it is close.
