Question

Diffusion is the spreading of gas particles into a wider and wider area as they intermingle with particles of other gases.

Option 1: True
Option 2: False

Answer 1

Diffusion is the process by which gaseous atoms and molecules move freely and randomly from regions of high concentration to regions of low concentration, resulting in a uniform composition of gases. This movement occurs even in the absence of mechanical agitation. Diffusion can be observed in liquids and solid solutions as well.

Step-by-step explanation:

Diffusion is the process by which gaseous atoms and molecules move freely and randomly from regions of high concentration to regions of low concentration, resulting in a uniform composition of gases. This movement occurs even in the absence of mechanical agitation. Diffusion can also be observed in liquids and solid solutions, although to a lesser extent.

In a closed environment, diffusion will eventually lead to equal concentrations of gases throughout the container. This is because the gas particles continue to move, but no net transfer of molecules occurs when their concentrations are the same in both regions.

For example, when you open a bottle of ammonia in a room, the ammonia gas molecules diffuse from the higher concentration in the bottle to the lower concentration at the edges of the room.
