Question

State which of the three states of matter solids, liquids or gases have

a) No definite volume.

b) A definite shape.

c) High density.

d) No free surface.

e) Particles that diffuse easily.

Answer 1

a) Gases do not have a definite volume because of the weakest intermolecular force of attraction.

b) Solids have a definite shape because of the strong intermolecular force of attraction between the particles. Hence particles are tightly compact with each other.

c) Solids have high densities

d) Gases have no free surface because due to large intermolecular space, molecules are far apart.

e) Particles of gases can diffuse easily because the kinetic energy of gas particles is very high due to the weak intermolecular force of attraction.
