Question 1 (Mandatory) (4 points) According to the phase diagram below the solid and liquid phases exist in equilibrium along line Pressure (atm) A) AD B) CB C) CD D) AB 1.0 0.7 D 15.0 30.0 Temperature (°C) 45.0 How many atoms are contained in a face centered cubic cell? Look at the picture to help your reasoning A) There are 14 atoms B) There are 8 corner atoms (only of each atom belongs to the cell) and 4 atoms on each of the faces of the cube (only of each atom belongs to the cell). Thus there is a total of 8x+4x=3 atoms. C) There are 8 corner atoms but only of each atom belongs to the cell and then there are 6 atoms on each face of the cube. There is a total of 8x+ 6-7 atoms D) There are 8 corner atoms (only 1 over 8 of each atom belongs to the cell) and 6 atoms on each of the faces of the cube (only 1 half of each atom belongs to the cell). Thus there is a total of 8 x 1 over 8+6x1 half = 4 atoms.
