Kinectic Theory Flashcards
What are the three physical states of matter?
Solid, liquid, and gas.
How do particles behave in a solid?
Particles have very low kinetic energy and vibrate around their fixed position.
How do particles behave in a liquid?
Particles have more kinetic energy and can move around each other.
How do particles behave in a gas?
Particles have high kinetic energy and move quickly in all directions.
What is the arrangement of particles in a solid?
Close together in a regular pattern.
What is the arrangement of particles in a liquid?
Close together in a random arrangement.
What is the arrangement of particles in a gas?
Far apart in a random arrangement.
What is the movement of particles in a solid?
They vibrate on the spot.
What is the movement of particles in a liquid?
They move around each other.
What is the movement of particles in a gas?
They move quickly in all directions.
How can we change the physical state of a material?
By changing the conditions it experiences.
What is needed to move from a solid to a liquid or from a liquid to a gas?
Heat.
What is needed to move from a gas to a liquid or from a liquid to a solid?
Cooling the system down.
What is diffusion?
The movement of gas from a high concentration to a low concentration.
What is a core practical example of diffusion?
The reaction between ammonia and hydrogen chloride.
