If a sample of neon gas occupies a volume of 2.8L at 1.8 atm. what will its volume be at 1.2 atm?
This problem asks us to make a comparison of the pressure and volume of a gas. The ratio of pressure and volume can be determined using Boyle's Law which is defined by the inverse relationship pressure to volume in the equation
For this question we identify the knowns and unknowns.
Notice that in Boyle's law as the pressure decreases the volume will increase as this is an inverse relationship between pressure and volume.
I hope this was helpful.
