Neon, when heat is added first the molecules, but only for a short period of time, move together, then they start speeding up and then they separate and when heat is taken away there is less energy and the molecules start to come together and then they freeze and still move, but as one. For Argon when heat is added they move as one and then they stay close together and start bouncing off each other and then it becomes a mad house when they start flying away when more heat is added. When heat is taken away from Argon they move left to right but the molecules stay together and then they slowly start to calm down and start to vibrate and eventually it even stops vibrating! One way to describe the molecules in oxygen is that when heat is added it looks like a huge group of friends (molecules), and then a fight (heat), happens and they all split into two friends (compounds) at a time and just burst off playing (spreading apart) in all directions. Water is a mixture that when heat is added to it, it just starts spinning and spreading apart. There are differences in these liquids, and those are the densities and the density tells you how long it will take to freeze and how long it will take to turn into a gas.
The more density the longer it takes for both of these process to happen. When i close the lid on the neon it spreads and then the top comes off. With Argon the more I move the lid closer the faster the molecules start to move and then the lid eventually comes off and the more Argon that I add the sooner it will pop. With the oxygen it lets me g down almost to the end with the lid, but then it does pop, but the more oxygen I add the less it lets me get closer to the bottom because then it becomes more dense. With the water what happen is that I keep going and I cram the molecules together until they fught so much they cant stand each other and then once again the lid comes off.
