Interparticle Forces of Attraction in Solids X, Y, and Z
Interparticle forces of attraction play a crucial role in determining the physical properties of solids. In this case, we are comparing the melting points of three solids X, Y, and Z, which have melting points of 298 K, 314 K, and 398 K respectively. Let's analyze the interparticle forces of attraction in these solids and arrange them in increasing order.
-

Solid X (Melting Point: 298 K)
Solid X has the lowest melting point among the three. This indicates that it has the weakest interparticle forces of attraction. The particles in solid X are held together by relatively weak forces, allowing them to break apart easily at lower temperatures. This suggests that solid X likely has predominantly weak forces such as London dispersion forces.
-

Solid Y (Melting Point: 314 K)
Solid Y has a higher melting point compared to solid X, indicating stronger interparticle forces of attraction. The particles in solid Y are held together by stronger forces than in solid X. This suggests that solid Y may have forces such as dipole-dipole interactions or hydrogen bonding contributing to its higher melting point.
-

Solid Z (Melting Point: 398 K)
Solid Z has the highest melting point among the three solids, indicating the strongest interparticle forces of attraction. The particles in solid Z are held together by very strong forces, requiring a higher temperature to overcome these forces and melt the solid. Solid Z likely has strong forces such as ionic bonds or metallic bonds contributing to its high melting point.

Arrangement in Increasing Order of Interparticle Forces:
Based on the melting points and the strength of interparticle forces discussed above, we can arrange the solids in increasing order of interparticle forces of attraction as follows:
1. Solid X (298 K) - weakest interparticle forces
2. Solid Y (314 K) - intermediate interparticle forces
3. Solid Z (398 K) - strongest interparticle forces
This analysis highlights the relationship between melting points and interparticle forces of attraction in solids X, Y, and Z.
