Question

Two solids a (melting point is 90 degree celsius) and b (melting point is 190 degree celsius) is provided.

1. Which solid has lesser force of attraction?
2. Which solid will absorb higher amount of latent heat of fusion for melting? ​

Answer 1

Solid b has lesser force of attraction than solid a. Solid b will absorb a higher amount of latent heat of fusion for melting compared to solid a.

Step-by-step explanation:

The force of attraction between particles in a solid is determined by the strength of the attractive forces operating within the solid. Generally, a solid with a higher melting point will have stronger forces of attraction between its particles. So, solid b, which has a melting point of 190 degrees Celsius, will have a lesser force of attraction compared to solid a, which has a melting point of 90 degrees Celsius.

For the second question, the amount of latent heat of fusion required to melt a solid depends on the strength of the attractive forces between its particles. A solid with stronger forces of attraction will require a higher amount of latent heat of fusion to break those bonds and melt. Therefore, solid b, with a higher melting point and stronger forces of attraction, will absorb a higher amount of latent heat of fusion for melting compared to solid a.
