Question
What are the characteristics of particles of matter?
Solution
- Matter is made up of small particles that humans cannot perceive with their naked eyes.
- Spaces exist between the particles of matter.
- Matter particles are attracted to one another by intermolecular interactions. Solids have the greatest attraction forces, whereas gasses have the least. Intermolecular forces exist between solids and gases.
- Matter particles are constantly moving rather than stationary.
- As intermolecular spaces expand, intermolecular forces decrease, and vice versa.
- The kinetic energy of molecules increases as the temperature rises.
