| Solids cannot be compressed. | Liquids can be compressed. Large pressure is required to compress them. | Gases can be compressed easily. |
| Solids have high density. | Liquids have lesser density than solids. | Gases have the least density among the three. |
| The force of attraction between the particles is very strong. | The intermolecular force of attraction is weaker than solids | The intermolecular force of attraction is weakest. |
| The space between the particles of solids is negligible. | They have considerable space between the particles. | The space between gas particles is large. |

A strong current of trivalent gaseous boron passed through a silicon crystal decreases the density of the crystal due to part replacement of silicon by boron and due to interstitial vacancies created by missing Si atoms. In one such experiment, one gram of silicon is taken and the boron atoms are found to be 1000 ppm by weight, when the density of the Si crystal decreases by 12%. The percentage of missing vacancies due to silicon, which are filled up by boron atoms will be ____ g. [Given · Atomic wt. Si= 30, B = 11]
