What is the kinetic theory
It is a theory that states that matter is made up of particles that are consistently in motion
What are the strong forces attraction that hold particles together called
Bonds
Describe the properties of a solid and movement of particles
A solid has a fixed shape and volume.
It's particles vibrate backwards and forwards but do not change positions
Describe the properties of a liquid and movement of particles
A liquid has a fixed volume and take she Shape of it's container.
It's particles are close together but vibrate vigorously so the forces if attraction cannot hold them in fixed positions.
Describe the properties and movement of a gas
Gases have no fixed shape or volume.
It's particles are far apart and move at high speeds, colliding with one another.
What is Brownian motion
Evidence for moving particles, suggests that particles drift through the air in zig-zag patterns
Who was"Brownian motion" named after
The scientist Robert brown
What is internal energy
Total kinetic and potential energy in all atoms / molecules in a material
What is the relationship between internal energy and movement
The more internal energy, the faster the movement
When a hot object comes in contact with a cold object what happens?
Internal energy or heat energy (thermal energy) is lost by the hit object and gained by the cold object
What particles where used when finding out the effect called Brownian motion
Smoke particles
