Final answer:
The state of matter that exhibits rapid diffusion is Gas (C). Gas particles move freely and quickly, allowing for diffusion to occur much more rapidly than in solids or liquids.
Step-by-step explanation:
The state of matter that has rapid diffusion through it is Gas (C). In gases, the particles are widely spaced and move rapidly in all directions, which facilitates the process of diffusion, leading to a uniform dispersal of matter. This is contrasted with solids, where particles are closely packed and have very limited movement, and liquids, where particles are closer than in gases but still capable of flowing and slowly diffusing.
In the context of the phases of matter:
- Gas allows molecules to move freely and spread out to fill the container.
- Liquid allows molecules to move about while remaining in contact.
- Plasma is similar to gas but consists of ionized particles.
- Solid molecules are tightly packed and only vibrate in place.
The properties of a substance with strong intermolecular forces, high melting point, and not easily compressed suggest that it would be a solid, as these are characteristic of solid materials.
