(b) In X-ray diffraction experiment at room temperature 300 K, there are three diffraction peaks 1, 2 and 3 as shown in picture. Intensy (relative) 40 50 60 70 80 90 100 WWW 20 30 Diffraction ange 20 When temperature increasing to 700 K to do the same experiment again, please describe what change happens for above X-ray diffraction pattern? And explain why do you think like this
