A string (str) object is an immutable sequence. In []: # Run the following to create a string variable named inflation. inflation = "increase in price" Question 1: Create a string with the last seven characters in inflation (i.e., a subsequence of inflation) and then store it in a variable named last7_upper. There are multiple ways to do the same thing. Use different indexing methods to have better understanding about Python indexing. In []: # Write your code in the space below after removing the ellipsis. last7_upper = ... #print(last7_upper)

Materials HW 6 1. Calculate the size (radius) of the critically sized nucleus for pure platinum when homogeneous nucleation takes place. (the answer for this one is in the back of the text, problem 4.32) $$r^* = -\frac{2\gamma T_{melt}}{(\Delta H_f \Delta T)} = \frac{2(240 \times 10^{-7} \frac{J}{cm^2})(2045K)}{(2160 \frac{J}{cm^3})(2045K)(0.2)} = 1.11 \times 10^{-7} cm$$ * $$\Delta H_f = 2160 J/cm^3$$ * $$\Delta T = 0.2 T_m = 0.2(2045K)$$ * $$\gamma = 240 \times 10^{-7} J/cm^3$$ * $$T_{melt} = 1772 ^\circ C = 2045 K$$ 2. Given the radius found above, how many atoms are in the platinum nucleus? VOLUME OF SPHERE $$V = \frac{4}{3}\pi r^3 = \frac{4}{3}\pi (1.11 \times 10^{-7} cm)^3 = 5.728 \times 10^{-21} cm^3$$ FCC UNIT CELL VOLUME $$V_{fcc} = a^3 = (\frac{4R}{\sqrt{2}})^3 = (\frac{4(1.11 \times 10^{-7} cm)}{\sqrt{2}})^3 = 3.094 \times 10^{-20} cm^3$$ CONVERSION USING FCC UNIT CELL $$= \frac{V_{fcc}}{\# atoms} = \frac{3.094 \times 10^{-20} cm^3}{4 atoms} = 7.736 \times 10^{-21} \frac{cm^3}{atom}$$ NUMBER OF ATOMS $$5.728 \times 10^{-21} cm^3 \times \frac{1 atom}{7.736 \times 10^{-21} cm^3} = 0.740 atoms$$
