In this problem we have a sample of nitrogen gas that is at a pressure of 67 .5 millimeters of mercury and is contained in a volume of 500 millimeters.
00:29
We need to calculate what would be the pressure of this nitrogen sample in a different container in a much smaller container with a volume of 125 millimeters okay so we need to calculate this new pressure we need to remember the law of ideal gas which states that the pressure times the volume of a gas is equal to the amount of gas in most times the constant of gas of the ideal gas times the temperature.
01:17
This transfer of the gas from the larger container to the smaller container takes place at a constant temperature.
01:30
And i know that because it's stated in the problem.
01:32
So this temperature is constant.
01:37
This is the constant of the idea gas, of the ideal gas, which doesn't change.
01:45
And the amount of gas, doesn't change.
01:47
They're not telling us that there is a change in the amount of gas.
01:52
Therefore, the product of the pressure and the volume will remain constant after the transfer, this product here...
