What is the process called when particles move from areas of high concentration to areas of low concentration?

Back

Diffusion

Front

What is the term for the movement of water across a semipermeable membrane?

Back

Osmosis

Front

Define 'high concentration area' in terms of particle arrangement.

Back

A high concentration area is where particles are tightly packed together.

What happens to a gummy bear when it is placed in salt water and why?

Back

The mass of the gummy bear decreases because water moves out of the gummy bear through osmosis.

What is the difference between diffusion and osmosis?

Back

Diffusion refers to the movement of any particles from high to low concentration, while osmosis specifically refers to the movement of water.

Front

What is a semipermeable membrane?

Back

A semipermeable membrane is a barrier that allows certain substances to pass through while blocking others.

How does temperature affect the rate of diffusion?

Back

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

Front

What is equilibrium in the context of diffusion?

Back

Equilibrium is the state reached when the concentration of particles is uniform throughout a space.

Front

What role do concentration gradients play in diffusion?

Back

Concentration gradients drive the movement of particles from areas of high concentration to areas of low concentration.

Front

Can diffusion occur in solids, liquids, and gases?

Back

Yes, diffusion can occur in solids, liquids, and gases, but the rate varies depending on the state of matter.
