Ideal gas problem after constraint removed

Click For Summary
SUMMARY

The discussion centers on solving an ideal gas problem where a constraint has been removed, leading to a scenario with four unknowns and only three equations. The initial pressures are denoted as P_1 and P_2, with final pressure P_f and final temperature T_f for both sections. The equations derived from the ideal gas law and conservation of energy highlight the necessity of including energy conservation to resolve the system completely. The lack of this constraint results in an insufficient number of equations to determine T_f definitively.

PREREQUISITES
  • Understanding of the ideal gas law
  • Familiarity with thermodynamic principles, particularly conservation of energy
  • Basic algebra for solving equations with multiple variables
  • Knowledge of pressure and temperature relationships in gas systems
NEXT STEPS
  • Study the ideal gas law and its applications in thermodynamics
  • Learn about conservation of energy in closed systems
  • Explore methods for solving systems of equations with multiple variables
  • Investigate the implications of removing constraints in thermodynamic problems
USEFUL FOR

Students and professionals in physics, engineering, and thermodynamics who are tackling problems related to ideal gases and energy conservation principles.

Attempt:
P_1 (initial pressure on the left section)
P_2(initial pressure on the right section)
T_f, P_f (final pressure for both sections)
P_1 (V/3) = N/2 k (3T/2)
P_2 (2V/3) = N/2 k (T/2)
P_f V/2 = N/2 k T_f
Resulting in 4 unknowns and 3 equations... Not enough to find T_f...

You forgot a constraint, namely conservation of energy.
