Density And Kinetic Theory Flashcards
What is the equation for density?
D = m/v
Density = mass ÷ volume
Descibe how particles are in a solid.
Particles are packed close together in a regular structure. They vibrate about fixed positions.
Describe how particles are in a liquid.
Particles are packed close together but are not fixed in position. They are free to move past each other.
Describe how particles are in a gas.
Particles are very far apart and move randomly in all directions.
Describe the density of a solid.
The particles of a solid are very close together.
Their density is high.
It melts when it changes from the solid state to the liquid state.
Describe the density of a liquid.
The particles are slightly further apart than a solid. They are slightly less dense than a solid.
Describe the density of a gas.
The particles are much further apart than a solid or liquid.
Their density is much less than a solid or liquid.
