%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \sect{Condensed boson molecules in eq with atoms constituents (Exam2003 Q2)} ${N}$ Bozon's molecules ${B}$ are inserted in to a box with volume ${V}$. Each molecule is composed from two atoms ${A}$. The atom's mass is ${\mathsf{m}}$ and the binding energy of the molecule is ${\varepsilon}$. The system's temperature is ${T}$. Some of the molecules are falling apart. Assume there are molecules in condensation state. Assume the un connected atoms can be treated in the Boltzman's proximity frame. How many (un connected) atoms are in e box? What is the condition for the Boltzman's proximity to be valid for the atoms? How many molecules are ed in arousing states? What is the condition for the condensation assumption to be valid? What is the pressure on the box'es walls? Who pressure's the most (The molecules ? the atoms ?).
