Question

Which of the following is not a characteristic of the solid state?
has a definite shape

particles are moving very fast

has a definite volume

particles are close together

particles are in fixed positions

Answer 1

Answer:

• The particles in a solid are held in a fixed position by bonds. This can be a lattice or it can be a more random arrangement of particles. Either way, they are fixed. The particles vibrate about their fixed position but they are always attached to the same neighbours.

Answer 2

Particles are moving very fast is not a characteristic of the solid-state. (OPTION B)

SOLID STATE -

• They have structural rigidity with definite mass, shape, and volume.
• They have a definite shape with high density.
• Particles remain fixed at their position and do not move.
• The particles vibrate and oscillate about their mean position.
• Particles are bonded very close to each other so the intermolecular distance is short due to strong intermolecular force.
