Roger Kisby/Getty Images Fans in the mosh pit during the performance of Liturgy at the 2012 Pitchfork Music Festival in Union Park, Chicago, on July 14, 2012. Physics and heavy metal don't seem to have a lot in common, but Matt Bierbaum and Jesse Silverberg have found a connection. Both are graduate students at Cornell University. They're also metal heads who enjoy going to concerts and hurling themselves into mosh pits full of like-minded fans. About five years ago Silverberg took his girlfriend to her first gig. While he was watching, he realized that the motion of people in a mosh pit looks kind of like molecules moving in a gas. "It was basically just this random mess of collisions, which is essentially how you want to think about the gas in the air that we breathe," he says. YouTube Note: This video contains profanity. Matter. What is matter?
Matter is everything around you. Atoms and compounds are all made of very small parts of matter. Those atoms go on to build the things you see and touch every day. Matter is defined as anything that has mass and takes up space (it has volume). What is mass? What is volume? Even though matter can be found all over the Universe, you will only find it in a few forms (states) on Earth. What are the main states of matter? What makes a state of matter? What is a physical change in matter? So what is a chemical change in matter? Physical changes are related to changes in the immediate environment such as temperature, pressure, and other physical forces.

States of Matter - Atomic Bonding, Chemistry, Heat. Topics Atomic Bonding Interaction Potential States of Matter Dipole Description Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Sample Learning Goals Describe a molecular model for solids, liquids, and gases.Extend this model to phase changes.Describe how heating or cooling changes the behavior of the molecules.Describe how changing the volume can affect temperature, pressure, and state.Relate a pressure-temperature diagram to the behavior of molecules.Interpret graphs of interatomic potential.Describe how forces on atoms relate to the interaction potential.Describe the physical meaning of the parameters in the Lennard-Jones potential, and how this relates to the molecule behavior.
