answeredWhen a sample of calcium carbonate is cooled, the temperature drop generally results in a decrease in kinetic energy for the molecules. As a result, they tend to vibrate less and the forces between them can strengthen, leading to a more rigid structure.
Therefore, the correct answer is:
B. The forces strengthen, and the molecule structure becomes more rigid.
