Answer 2

Answer:

(A) Solids have a fixed shape and a fixed size. The particles are very close together and held in place by strong forces (bonds). Their particles cannot move around, but they do vibrate. Because the particles cannot move around, a solid has a fixed shape.

(B) Gases have neither fixed shape nor fixed volume. This is because of the weak intermolecular foces of attraction in the gases. They take the shape and volume of the container in which they are placed.
