Question

Which of the following best describes how attractive forces of the molecules in a solid compared to a liquid?

A)The attractive forces are the same in a solid and liquid
B) The attractive forces are stronger in a liquid
C) The attractive forces are stronger in a solid
D)The attractive forces of a solid allow the particle to move freely while the liquid molecules vibrate around a fixed point

Answer 1

Option-C (The attractive forces are stronger in a solid)

Step-by-step explanation:

The substance either exist as a Solid or Liquid depends upon on the following two factors;

ii) Kinetic Energy:

Greater the K.E of particles, greater will be the distance between the particles of a substance. In Liquids the K.E of particles is greater than the K.E of particles in Solid. Hence, the Liquid Particles separated by greater distance as compared to particles of Solids.

ii) Attractive Intermolecular Forces:

Greater the Attractive Intermolecular Forces between the particles of a substance, smaller will be the distance between the particles. As the distance between the particles in Solid state of substance are very small as compared to that of Liquids hence, it can be concluded that the Attractive Intermolecular Forces in Solids are stronger than Liquids.
