Diffusion

Front

What is diffusion?

Back

Diffusion is the process by which particles spread from an area of high concentration to an area of low concentration until they are evenly distributed.

Front

What factors affect the rate of diffusion?

Back

The rate of diffusion is affected by temperature, concentration gradient, and the size of the particles.

Front

How does temperature affect diffusion?

Back

An increase in temperature speeds up diffusion because particles move faster at higher temperatures.

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in the concentration of particles in two different areas.

Front

What happens to diffusion when the concentration of particles is equal?

Back

Diffusion stops when the concentration of particles is equal throughout the system.

Front

What is thermal expansion?

Back

Thermal expansion is the increase in volume of a substance when it is heated.

Front

Why does a heated liquid overflow?

Back

A heated liquid overflows because its volume expands when heated.

Front

What is kinetic energy?

Back

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

Front

How does the speed of an object relate to its kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

What is the end result of diffusion?

Back

The end result of diffusion is an even distribution of particles throughout the space.
