Diffusion

Front

What is diffusion?

Back

Diffusion is the movement of particles from an area of high concentration to an area of low concentration.

Front

What effect does an increase in temperature have on diffusion?

Back

An increase in temperature speeds up diffusion.

Front

What is equilibrium in the context of diffusion?

Back

Equilibrium is a state where the concentration of molecules is consistent throughout a space, meaning there is no net movement of particles.

Front

Which gases move into and out of the blood at the lungs by diffusion?

Back

Oxygen and Carbon Dioxide.

Front

What causes diffusion to occur?

Back

Diffusion is caused by the constant, random motion of molecules.

Front

What is concentration in relation to diffusion?

Back

Concentration refers to the amount of a substance in a given volume; in diffusion, particles move from areas of high concentration to low concentration.

Front

Can diffusion occur in solids?

Back

Diffusion occurs primarily in liquids and gases, but it can happen in solids at very slow rates.

Front

What is the role of diffusion in the human body?

Back

Diffusion allows for the exchange of gases (like oxygen and carbon dioxide) in the lungs and the absorption of nutrients in cells.

Front

How does temperature affect the rate of diffusion?

Back

Higher temperatures increase the energy of molecules, leading to faster diffusion rates.

Front

What is a real-life example of diffusion?

Back

A real-life example of diffusion is the smell of perfume spreading in a room.
