Question

Gases diffuse very fast. Why ?

Answer 1

• Diffusion is the process of intermixing particles of different types of matter (solids, liquids, and gases).
• Diffusion causes the particles to move from a region of high concentration to a lower concentration.
• Gases show the maximum rate of diffusion while solids show the least rate of diffusion.
• Due to the large space among the particles of gases and weak intermolecular attraction, gases show diffusion at a fast rate.
• On increasing the temperature or supplying heat, the particles of gases gain energy and start moving with more velocity.
• Hence, increasing temperature increases the rate of diffusion.
