The figure shows three rectangular blocks made from the same material. The initial dimensions of each are expressed as multiples of D, where D = 2.00 cm. The blocks are heated and their temperatures increase by 35.0 o8. The coefficients of linear and volume expansion are a = 1.50 × 10-5 (Co)-1 and β × 4.50 × 10-5 (Co)-1, respectively. Concepts (i) Does the change in the vertical height of a block depend only on its height, or does it also depend on its width and depth? Without doing any calculations, rank the blocks according to their change in height, largest first. (ii) Does the change in the volume of a block depend only on its Height, or does it also depend on its width and depth? Without doing any calculations, rank the blocks according to their change in volume, largest first. Calculations: Determine the change in the (a) Vertical heights and (b) Volumes of the blocks?
