Understand the concept of diffusion: Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. It is driven by the kinetic energy of the particles.
Identify factors that affect diffusion: The rate of diffusion can be influenced by several factors, including temperature, concentration gradient, and the medium through which diffusion occurs.
Explain the role of temperature: Temperature affects the kinetic energy of particles. Higher temperatures increase the kinetic energy, causing particles to move faster and thus increasing the rate of diffusion.
Consider other factors: While the color of the substance, type of solvent, and shape of the container might seem relevant, they do not directly affect the kinetic energy of the particles involved in diffusion.
Conclude with the correct factor: Among the options given, temperature is the factor that directly affects the rate of diffusion by altering the kinetic energy of the particles.
