Answer:
Attractive forces between particles
Explanation:
There are three states of matter i.e solids, liquids and gases. All three states have different properties. A solid keeps its shape due to attractive forces between particles. These forces are called inter molecular forces. The particles of solid keeps with this force. There are few types of inter molecular forces
- Ionic bonds
- Van-der-Waals dipole-dipole interactions
- Hydrogen bonding
- Van-der-Waals dispersion forces.
Hence, the correct option is (b) "Attractive forces between particles".
A solid keeps its shape due to the attractive forces between particles.
Solids have their own shape and volume.
The particles that compose them are very ordered and the attractive forces between them are very large, so they do not flow and are very rigid.
About solids:
- Its particles are oscillating around "fixed" positions of maximum stability.
These positions or distances between atoms, of maximum stability are those that present the maximum attractive forces and the minimum repulsive forces.
- The forces between the particles of a solid are high enough so that the cohesion of the crystal is maintained.
This is due to the fact that the attractive forces are very intense and the particles are only free to carry out small vibrations and that is why solids have constant shape and volume.
Therefore, we can conclude that a solid keeps its shape due to the very intense attractive forces between particles.
