Kinetic Particle Theory Flashcards
All matter is made up of _____ _____ that are too small to be seen directly.
Discrete particles
There are _____ between particles of matter; the amount of space between particles is different in _____, _____, _____. The average amount of empty space between molecules gets progressively _____ as sample of matter moves from the solid to the liquid and gas phases.
Spaces
Liquids,Gases,Solids
Larger
Solids ____ be compressed
Liquids______ be compressed
Gases ______ be compressed
Cannot
Cannot
Can
The particles of matter are in ____________________; particles move at different speeds in _____,______, ______.
Constant random motion
Gases,liquids,solids
The 😭_______of a substance is a measure of the average __________ Of the particles. A change in phase may occur when energy of particles is changed.
Temperature
Kinetic energy
What is a real gas?
Non-hypothetical gases.
What is an ideal gas?
Hypothetical gas
Particles
Ideal=made of small particles that have mass
Real=Same
Space
Ideal=mostly empty space
Real=SAME
Density
Ideal=density
Real=SAME
Motion
Ideal=gas particles are in constant random straight line motion
Real=SAME
Attractive or repulsive forces between particles
Ideal=NONE
Real=VERY SMALL
Volume
Ideal=NO volume
Real= VERY SMALL volume
Collisions
Ideal=ELASTIC (no loss in kinetic energy)
Real=NON-ELASTIC (they will lose energy)
