| Question | Answer |
|---|---|
| kinectic molecular theory | matter is always in motion |
| properties of gases 1 | move fast and take up a lot of space |
| property of gases 2 | collide with each other in their container |
| property of gases 3 | motioln equals kinectic energy = mass velocity squared |
| property of gases 4 | amount of energy depends on temp |
| property of gases 5 | gases do not attract each other |
| expansion | ggases dont have definite shape or volume. they fill any container in which they are enclosed |
| fluids | a substance that can flow and thus take the shape of the container |
| compressability | gas particles that start out far aprt become crowded close together the volume of the gas sample can be reduced |
| diffusion | spontaneous mixing of particles of 2 substances caused by there random motion |
| effusion | a process by which gas particles pass through a tiny opening |
| ideal gas | an imaginary gas the perfectly fits all the assumptions of kinectic molecular theory |
| elastic collisioon | a collision in which there is no loss of kinectic energy |
| units of pressure | 1 atm=750mlhg=760torr |
| measurement of average energy | hot is mmore motion cold is less motion |
| 0k | is the temp at whichall motion stops |
| stp | 1atm=273k |
| boyles law | p1b1=p2b2 |
| charlses law | b1overt1=b2over t2 |
| gay lussacs law | p1/t1=p2/t2 |
| avogadros law | b1/n1=b2/n2 |
| combined gas law | p1b1/t1n1=p2b2/t2n2 |
| daltons law of partial pressures | ptotal=pa+pb+pc |
