So for this problem, we're dealing with a spherical glass container that has an unknown volume, and it contains helium gas at a temperature of 25 degrees celsius, which is going to be 298 kelvin, because we had 25 plus 273 to turn celsius into kelvin.
00:27
It has a pressure of 1 .1.
00:32
1 .960 atm.
00:36
Now, a portion of the gas is taken and adjusted to 1 atm at 25 degrees celsius, and it's found to have a volume of 1 .75 centimeters cubed.
00:52
The gas remaining in the first container ends up, the pressure ends up converting or changing to 1 .7108.
01:03
Inside of that original container, and we're trying to find the volume of the spherical container.
01:09
So we know that we took off enough to have a volume of 1 .75 sunrays cube, 1 atm, and again our temperature is still 25 degrees celsius or 298 kelvin.
01:26
So what we can do here to solve for our answer is we can use the p, v1 equals p2v2...
