Properties of gas

Today in science class we talked about pressure and gas. We talked about if you put water in a pot and put a lid on it and then add heat. Evaporation would occur. It would go up into the lid and come back down into the pot. When the water begins to boil, there would be so much pressure that the top would begin to shake letting H2O escape. If you boiled water without a lid, the evaporation would go into the air and when it starts to boil and then when the pot cannot hold the h2o any more it over flows. Then after that we went on this really cool website that showed us exactly what happened when you add pressure and heat. For the first thing it was just showing you what happens when you add heat or take heat away from water, oxygen, neon, argon. The second one showed what happened when you put pressure on water, neon, oxygen, and argon. These experiments were very fun and in my opinion was a great way to learn what we were studying about.
