This set of Materials Science Multiple Choice Questions & Answers (MCQs) focuses on Answer: d Explanation: At normal conditions probability of occurrence of an adjacent interstitial site is Answer: b Explanation: Osmosis is a special type of diffusion where an SPM separates two liquid solutions.Diffusion, Osmosis & Active Transport. Practice Test Questions. d. osmosis. 4. Diffusion is when molecules of a substance move from a higher concentration to a lower concentration. Which of the following factors do NOT affect the rate of diffusion?(d) Now, reinterpret the problem as a random walk with step-length a and time-step τ. Without taking any limits, show that the continuum probability distribution can be written as ! P(X,t)= 1 4"Dt e # (X#vt)2 4Dt, where ! v= a(p"q) # is a drift velocity and ! D= 2pqa2 " is a diffusion coefficient.
