Amaterial with a cubic unit cell is heated from room temperature to 900°c without melting during this time, the bragg peaks in the x-ray diffraction pattern are seen to increase in width. the 20 position of the peak decreases over the same temperature range. explain these a) observations on an atomic scale. (note the mark allocation, there are 2 observations that need separate explanations)
