Understanding Diffusion
Diffusion is the process by which particles spread from an area of high concentration to an area of low concentration. This movement occurs due to the kinetic energy of the particles.
State of Matter: Solid vs. Liquid
In solids, particles are closely packed together and vibrate in fixed positions. This arrangement restricts their movement, leading to a slower rate of diffusion.
In contrast, when a substance changes from a solid to a liquid, the particles gain energy. This energy allows them to overcome the forces holding them in place, resulting in a more fluid arrangement.
Effect on Diffusion Rate
- Increased Movement: In liquids, particles are more mobile compared to solids. They can move freely, allowing them to spread out more quickly.
- Higher Kinetic Energy: The transition to liquid state increases the kinetic energy of particles, making them collide and mix faster.
- Greater Space: The arrangement in liquids provides more space for particles to move around, enhancing their ability to diffuse.
Conclusion
When a substance changes from a solid to a liquid, the rate of diffusion increases (option 'C'). This is due to the enhanced movement, higher kinetic energy, and greater space available for the particles in the liquid state, all contributing to a faster diffusion process.

The rate of diffusion increases when a substance changes from a solid to a liquid. In liquids, particles are less tightly packed and can move more freely compared to solids, allowing for faster diffusion.
