Question

2. Which of the following statements about solidification is incorrect? (a) systems with only an excluded volume interaction are athermal (b) cohesion in materials is governed by potential energy (electrostatic) but solidification is largely driven by entropic considerations (c) for classical hard spheres, the hcp and fcc configurations (ABAB and ABCABC layer stacking, respectively) are degenerate; both correspond to close packing (d) for classical hard spheres, the ordered phase at temperature T > 0 is a state of low entropy

Answer 1

Which of the following statements about solidification is incorrect? (a) systems with only an excluded volume interaction are athermal (b) cohesion in materials is governed by potential energy (electrostatic) but solidification is largely driven by entropic considerations (c) for classical hard spheres, the hcp and fcc configurations (ABAB and ABCABC layer stacking, respectively) are degenerate; both correspond to close packing (d) for classical hard spheres, the ordered phase at temperature T > 0 is a state of low entropy

Explanation:

Option D is incorrect

(d) for classical hard spheres, the ordered phase at temperature T > 0 is a state of low entropy
