## States of Matter Basics

Note that the interactive elements in this sim have simple description that can be accessed using a screen reader. Push the pump and change the volume of matter in the closed container. Build circuits with batteries, resistors, light bulbs, and switches. More advanced students can compare the potential energy graphs for neon, argon, oxygen, and water which all have different interaction potential. Then play a game to test your ideas! More advanced students can compare the potential energy graphs for neon, argon, oxygen, and water -- which all have different interaction potential. View the electric field, and measure the voltage. The total thermal energy sometimes called the total internal energy of a system depends jointly on the temperature, the total number of atoms in the system, and the state of the material.

Build your own tracks, ramps, and jumps for the skater. This simulation helps learners visualize how molecules behave in solids, liquids, and gases. In gases, the atoms or molecules have still more energy and are free of one another except during occasional collisions. Many forms of energy can be considered to be either kinetic energy, which is the energy of motion, or potential energy, which depends on the separation between mutually attracting or repelling objects. .

In solids, the atoms or molecules are closely locked in position and can only vibrate. Create models of dipoles, capacitors, and more! Customize the attraction to see how changing the atomic diameter and interaction strength affects the interaction. Elastic energy is associated with the stretching or compressing of an elastic object. Measure the period using the stopwatch or period timer. Visualize the sizes and distances between different heavenly bodies, and turn off gravity to see what would happen without it! View the light as a solid beam, or see the individual photons. Play with prisms of different shapes and make rainbows.

Energy appears in different forms and can be transformed within a system. The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present. Explore vector representations, and add air resistance to investigate the factors that influence drag. Observe the the total force acting on the atoms or the individual attractive and repulsive forces. Temperature is not a direct measure of a system's total thermal energy. More advanced students can compare the potential energy graphs for neon, argon, oxygen, and water -- which all have different interaction potential.

Change the voltage and see charges build up on the plates. Electrical energy is associated with an electric current in a circuit. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Motion energy is associated with the speed of an object. Push the pump and change the volume of matter in the closed container and watch the pressure gauge respond.

Test what you've learned by trying the Balance Challenge game. Simulations are often useful in modeling events and processes. Contains links to quickly access the simulations and multiple screenshots from the simulations to assist students in completing the activity. Please refer to the style manuals in the area for clarifications. Relate the interaction potential to the forces between molecules. The details of that relationship depend on the type of atom or molecule and the interactions among the atoms in the material.

Explore different tracks and view the kinetic energy, potential energy and friction as she moves. No matter how substances within a closed system interact with one another, or how they combine or break apart, the total mass of the system remains the same. Even observe a string vibrate in slow motion. Adjust properties of the objects to see how changing the properties affects the gravitational attraction. Electric forces acting within and between atoms are vastly stronger than the gravitational forces acting between the atoms. Learn about projectile motion by firing various objects. Change the size of the plates and the distance between them.

Notice the anharmonic behavior at large amplitude. Transport the lab to different planets. Investigate what happens when two springs are connected in series and parallel. They are also used for processes that are too vast, too complex, or too dangerous to study. Add or remove heat and watch the motion of the molecules as they change phase. Heat, cool and compress atoms and molecules and watch as they change between solid, liquid and gas phases.
