einstein model take that in solid state, there are 3N normal mode vibration that all have the same mode frequency of ω0. the density of states σ(ω) for this model is

σ(ω) = δ(ω − ω0) .

a. with the given information, and by neglecting the zero point energy, calculate the total energy and the heat capacity Cv in this solid state model.

b. when the temperture is high, show that Cv → 3N kB. this value is often called Dulong-Petit value.

Consider a case in which we have an Einstein solid that is neither at high or low temperature. In this case, we cannot use either the N>>q or q>>N approximation. In this case both N and q are >> 1. Derive an expression for the chemical potential then discuss how this more general result differs from and/or could correlate to the low and high temperature cases. Thermodynamics

ARCHITECTURE Take one façade of your chosen building and assume (for this exercise) that all solid portions are precast concrete. Diagram the flow of forces showing primary and secondary forces and differentiating tensile forces from compressive ones. propose a new shape for the façade that is more efficient and expressive of the flow of forces. It is important that you pick a façade that is not completely glass and includes some continuous nonglazed portions from top of wall down to...

You have completed a reaction and take the melting point of your resulting solid product and the melting point you measured on the melt-temp is 130 – 142°C. The product you were trying to make was chloramphenicol which has a literature melting point of 150 - 151.5°C. (A) What are two possibilities for why your melting point is different from the literature melting point? (B) How would you figure out which of your two possibilities actually happened?
