2. Which of the following statements is NOT true regarding the surface of a solid? a. The atoms have the same bonding and arrangement as in the bulk crystal b. It becomes more important in determining properties as particles get smaller c. The surfaces differ based on how they are formed (i.e. how the crystal is cut) d. It has long range order 3. What is false about the eutectic point of a solution composed of two liquids? a. The eutectic point indicates the freezing temperature of any solution composition resulting from mixing the two liquids b. At the eutectic point, the chemical potential of the solution is equal to that of both solids c. The eutectic point represents a phase transition from the solution to solid d. The eutectic point is always at a lower temperature than the freezing point of either of the pure liquids 4. Liquids primarily differ from gases and solids in that? a. They always have a higher density than gases and a lower density than solids b. They have higher potential energy than both gases and solids c. They have the largest intermolecular forces d. They are more structured than gases and less structured than liquids

2.
a. The atoms have the same bonding and arrangement as in the bulk crystal is Not true statement regarding the surface of a solid.
- Since there are two types of crystalline and amorphous solids.
- Amorphous solids don't have their constituent parts arranged in regular arrays like those found in crystalline solids, which are held together by homogeneous intermolecular forces.
