An elastic collision is
When particles bounce without losing energy
This tool measures air pressure
Barometer
Gases are made of tiny _____.
Particles
Smelling popcorn across the room, is an example of what?
Diffusion
Gases are easy to compress, why?
There is empty space between particles
Diffusion is
Movement from high to low concentration
The kinetic-molecular theory explains what
How gas particles move and behave
Temperature affects gas particles how?
Higher temperature equals faster particle
Balloon shrinking in the freezer, shows what?
Lower temperatures slowing particles
Explain the difference between diffusion and effusion.
Diffusion spreads in open space.
Effusion escapes through a small hole.
Grahma's law of effusion explains what?
Lighter glasses move faster than heavier gases
Why does a balloon shrink in cold weather?
Particles slow down and hit less walls
Pressure is
Pumping air into a tire, is an example of what?
Compression

collide
Higher temperature means higher ____ energy.
kinetic
Gas particles are in constant
____.
motion
Why can a air be compressed but not a rock?
Gas particles are far apart with empty space, while a rock's particles are tightly packed with no space between them.
Helium escaping faster then oxygen is an example of?
Graham's Law
According to Dalton's Law, how do you find total pressure?
By adding the pressure of each gas together
