Front

What is diffusion?

Back

The process by which particles move from an area of high concentration to an area of low concentration.

Front

Where does diffusion occur?

Back

In gases, liquids, and across membranes.

Front

What is a solute?

Back

A substance dissolved in another substance.

Front

What is a solvent?

Back

The substance doing the dissolving.

Front

What does 'high concentration' mean?

Back

A region where particles are tightly packed together.

Front

What does 'low concentration' mean?

Back

A region where particles are spread out.

Front

What is a concentration gradient?

Back

The difference in concentration of a substance between two areas.

Front

What factors affect the rate of diffusion?

Back

Temperature, concentration gradient, and the size of the particles.

Front

How does temperature affect diffusion?

Back

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

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.
