For the first part of this question, we want to know if we start with a volume of 3 .09 liters of a given gas at a pressure 4 .23 atmospheres.
00:13
And then that pressure has changed to 9 .98 atmospheres.
00:18
What would the final volume be? so for this first part, we're going to be using boyle's law.
00:25
And so for this law, we have a formula stating the initial pressure times the initial volume is equal to.
00:33
To the final pressure times the final volume.
00:37
And this is an inverse relationship.
00:39
So our volume should be going down.
00:41
So our second volume should be lower than our first one.
00:45
So we're going to plug our numbers in.
00:48
So we have our initial values of 3 .09 and 4 .23.
00:59
And then we have our final pressure of 9 .98.
01:05
And we don't know our final volume.

For your unknown quantity, you can really use any variable you want...
