Please not Ai generated, show all steps in need to understand. Use table vaules thermodynamics engineering aprproch 10th.

The question is in the picture.. Please don't skip the simple steps

The second virial coefficient is related to pair-wise potential function via B(T) = 2πNA (1- e-/kr) r²dr. Use the hard sphere pairwise potential function to find B(T).

Discuss the importance of the Bernoulli equation. List and describe at least 5 examples of applications of the Bernoulli equation, and discuss and elaborate the different limitations of the use of the Bernoulli equation.

Exercise 3: Crystalline domain size The Full Width at Half Maximum (FWHM), for a Bragg reflection occurring at 20 = 74.187 0, is 3.306 °. Estimate the crystalline domain size assuming: K = 0.9; B₁ = 0.050; and λ = 1.5418 Å.
