Solids

Solids

1. Why do solids have fixed shape?

According to the kinetic particle theory of matter the particles in solids

1.     Are tightly packed in an orderly manner;

2.     Are held together by strong attractive forces;

3.     Have just enough kinetic energy to vibrate or rotate about their fixed positions

4.     Cannot move freely

2. Why do solids have fixed volume?

Solids cannot be compressed as there is very little space between the particles; they are packed close to each other. The distance between the particle is minimum. Hence they have fixed volume.
