Find solns

Q5. Two different objects are shown below consisting of different lines (Li. Ly, Ly . and one Arc of radius R. Which statement is true for this configuration? LI LI LA a) Same geometry and same topology b) Different geometry and different topology Same geometry but different topology d) Different geometry but same topology Page 3 of 1Note: for statistical mechanics problems, you may use the following numbers of congurations] microstates depending on the phase of the system (ideal gas, 9, liquid, 1, or solid, 5): 1. Communal Entropy. The difference in entropy upon melting of a solid is commonly referred to as the "communal entropy," and for a crystalline solid is predominantly due to the difference in congurational entropy of the resulting liquid (denoted by I) compared to the initial solid (denoted by s): rms 2' sdlsconfig = configJ Sconfig Use statistical mechanics to find a simple expression for drugs by assuming that the molar (or molecular) volume of the solid and liquid are approximately equal. Hint: you will need to employ Stirling's formula (Equation 1.? in Simon 9 McQuarrfe). 15. Derive the vibrational partition function at the high-temperature limit (T - co). 16. Use the particle in the 3-D box model to calculate the translational energy difference (AE = E2 - 81) for the molecular nitrogen (N2) and compare it with the available thermal energy at 298 K (take the length of the box to be I cm). 17. Using statistical mechanics, derive the molar entropy of monoatomic ideal gas
