NYS Diffusion Part 1

Front

What is osmosis?

Back

The diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration.

Front

What is diffusion?

Back

The movement of particles from an area of high concentration to an area of low concentration.

Front

What happens when distilled water is compared to salt water?

Back

Distilled water is a higher concentration of water, while salt water has a lower concentration; thus, things diffuse from high to low concentration.

Front

What does 'high concentration area' mean?

Back

It means that particles are tightly packed together.

Front

What is a semi-permeable membrane?

Back

A barrier that allows certain substances to pass through while blocking others.

Front

What is the main difference between osmosis and diffusion?

Back

Osmosis specifically refers to the diffusion of water, while diffusion can refer to any type of particles.

Front

What is an example of diffusion in everyday life?

Back

The smell of perfume spreading in a room.

Front

What is the role of concentration gradients in diffusion?

Back

Particles move from areas of high concentration to areas of low concentration, following the concentration gradient.

Front

What is equilibrium in the context of diffusion?

Back

A state where the concentration of particles is equal throughout a space.

Front

How does temperature affect the rate of diffusion?

Back

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