Questions: Which statement best describes the process of diffusion? The process by which a gas spreads through a space occupied by another gas

Solution Steps

Diffusion is a process that involves the movement of particles from an area of higher concentration to an area of lower concentration. This process continues until there is an even distribution of particles.

1. "The process by which a gas escapes from a container into a vacuum through a small hole" describes effusion, not diffusion.
2. "The process of preparing a less concentrated solution from a more concentrated solution" describes dilution, not diffusion.
3. "The process by which a gas spreads through a space occupied by another gas" correctly describes diffusion.
