How does increasing temperature affect the diffusion of a gas?

Increasing the temperature of a gas increases the energy of its particles. As temperature rises, the kinetic energy of the gas molecules also increases, resulting in faster movement of the particles. This heightened motion allows gas molecules to collide and spread out more rapidly, leading to enhanced rates of diffusion.

In the context of diffusion, which is the process where gas particles move from an area of higher concentration to an area of lower concentration, the increased energy at higher temperatures allows the particles to overcome intermolecular forces more easily and travel faster. This means that as temperature rises, the rate of diffusion is positively affected and occurs more quickly.

The other options suggest scenarios that do not accurately reflect the principles of kinetic theory and gas behavior. For example, the idea that gas diffuses slower due to increased density misrepresents the relationship between temperature and particle energy. Similarly, stating that gas diffusion remains constant regardless of temperature does not take into account how kinetic energy influences molecular movement, while the claim that gas cannot diffuse at higher temperatures contradicts the fundamental understanding of gas behavior in thermodynamics.
