All right, so we have a number of statements about gases and we're asked to determine whether each is true or false.
00:06
So a lot of these will be based on the kinetic molecular theory and the gas laws.
00:10
So i'll reference those.
00:11
All right.
00:12
So if we have a gas, it's made of of small particles.
00:14
That's true.
00:15
They move randomly.
00:16
That's true.
00:17
But not at low speeds.
00:19
Gases tend to move at high speeds.
00:21
That's in the kinetic molecular theory.
00:23
They move rapidly and randomly.
00:25
So the statement as written is going to be false.
00:28
All right.
00:28
Average kinetic energy directly proportional to the kelvin temperature, that is true.
00:33
If you look at kmt, that is true.
00:35
All right, gas can be described by pressure, volume, temperature, and quantity.
00:38
Quantity normally in moles.
00:40
That's true, and that's why those are the four variables in the ideal gas law.
00:46
All right.
00:47
One atmosphere is 760 pascal's.
00:53
Nope, one atmosphere is 760 millimeters of mercury.
00:57
It's equal to like 100 and basically this 1001 ,300 pascals or 101 .3 kilopascals.
01:09
So this is false...
