1) a crystal has a coefficient of expansion 13* in one direction and 231 * in every direction at right angles to it then the cubical coefficient of expansion is: 2) a barometer having a brass scale reads 77.24 cm at a temp of 20c the scale is graduated to b accurate at 0c what would b the reading at 0c coeff. of cubical expansion of mercury= 18 * coeff of linear expansion of brass= 19 *
