A.
As the density of a substance increases, the attraction among its particles increases.
Explanation:
The relationship between density and particle attraction is that as the density of a substance increases, the attraction among its particles increases.
- Density is the function of the mass and volume of body.
- Mass is the amount of particles a substance contains. It is directly related to the density.
- Volume is the amount of space a substance occupies. It is inversely related to the density.
- A substance will have a large volume if it is poorly packed and the attraction between particles is very weak or low.
- Particles that are well packed have high attraction between their particles. This reduces their volume and the density will increase.
