Hi there.
00:04
In this question, we are told that the temperature and the pressure are constant.
00:14
So only the number of moles and the volume are changing.
00:18
So this is described by avogadro's law.
00:24
Avagadro's law says that when temperature and pressure are constant, then the number of moles of a gas and the volume are directly proportional.
00:36
So that means that adding two additional units of the gas, in this case moles, will give us two additional units of volume.
01:19
In other words, we're going to see the volume of this syringe increase by two more units.
01:25
So if we think of that first one as being one unit and we add two more, we're going to end up with a volume that is three times the original amount.
01:34
So as we look at these pictures, number one has more moles of gas and more volume, but for some reason, it's just showing the moles of gas sitting on the bottom, which gas particles do not do.

They move throughout their entire container...
