Advisory - Diffusion

Front

What is diffusion?

Back

Diffusion is the process by which molecules move from an area of high concentration to an area of low concentration.

Front

When does diffusion stop?

Back

Diffusion stops when the particles are evenly spread out.

Front

How does temperature affect diffusion?

Back

An increase in temperature speeds up diffusion.

Front

What happens to particles when they are heated?

Back

When particles are heated, they speed up and spread out.

Front

What is kinetic energy?

Back

Kinetic energy is the energy that an object possesses due to its motion.

Front

How does kinetic energy relate to temperature?

Back

As the kinetic energy of the molecules in a substance increases, the temperature of the substance increases.

Front

What is concentration in the context of diffusion?

Back

Concentration refers to the amount of a substance in a given volume.

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in concentration of a substance between two areas.

Front

What role does the concentration gradient play in diffusion?

Back

The concentration gradient drives the movement of molecules from high to low concentration.

Front

Can diffusion occur in solids?

Back

Diffusion occurs primarily in liquids and gases, but it can also occur in solids, though at a much slower rate.
