Page 1 Materials 1M03, Test #1 2010 Feb. 2, 2010 Version (1) Page 1 of 7 Model Solutions MATERIALS 1M03 TERM TEST #1, 2010 Time: 90 Minutes This test contains 13 questions. You are responsible for ensuring that your copy of the paper is complete. Bring any discrepancy to the attention of your invigilator. SPECIAL INSTRUCTIONS: Aids allowed: 1 double-sided page crib sheet, nominally 8½ by 11 in. McMaster standard Casio FX-991 calculator Answer all multiple choice questions on the special answer sheet only. There are 12 multiple choice questions each is worth 2 marks. There is one written question, worth 6 marks. Answer this question on the examination copy. Be sure to show your work so that part marks can be awarded for incomplete answers. Be sure to include units with all answers that require them. Useful constants: Gas constant, R = 8.31 J/mol-K Charge per electron, e = 1.6 x 10 -19 C Avogadro’s number, N A = 6.02 x 10 23 Boltzmann’s constant, k = 1.38 x 10 -23 J/atom-K = 8.62 x 10 -5 eV/atom-K 1cal =4.184J MC ___/24 Q13 ___/6 Total ___/30

Page 2 Materials 1M03, Test #1 2010 Feb. 2, 2010 Version (1) Page 2 of 7 Part A: This part consists of TWELVE multiple choice questions, worth 2 marks each. Put your answers on the scan sheet (marked McMaster University Examination Answer Sheet). Read the Marking Directions on this sheet carefully before starting. 1. Determine the Miller indices of the direction shown in Fig. 1, below: x y z ½ Figure 1: (a) ] 210 [ (b) ] 10 [ 2 1 (c) ] 0 1 2 (d) ] 120 Distance travelled in x direction is 1/2. Distance travelled in the y direction is 1. Distance travelled in the z direction is 0. So, ½ 1 0 Clear fraction to get: [1 2 0] or (d)

Determine the Miller indices of the direction shown in Fig. 2, below: x y z ½ 1/3 Figure 2: (a) [ 3 4 6] (b) [ 4 3 (c) [634] (d) [ 3 4 2 ] Distance travelled in x direction is 1. Distance travelled in y direction is -1/2 Distance travelled in z direction is -2/3 So 1 -1/2 -2/3 Clear the fractions to get: [ 4 3 6 ] or (b)
