Heat, a form of energy that transfers from matter at higher temperatures to matter at lower temperatures, the 3 states of matter, solid, liquid, gas, freezing point, where water changes from liquid to solid at 0 degrees Celsius, melting point, where water changes from solid to liquid at 0 degrees Celsius, boiling point, where water changes from liquid to gas at 100 degrees Celsius, condensation point, Where water changes from gas to liquid at 100 degrees Celsius, kinetic energy, energy of movement, the particle model of matter, All matter is made of tiny particles. The tiny particles are always moving. The particles have space between them. Adding heat makes the particles move faster., volume, the amount of space that matter occupies, Solid, In this state, particles are packed closely together and vibrate back and forth. These have a fixed shape., Liquid, Matter in this state takes the shape of its container, and bonds that hold particles together are weak., Gas, Particles in this state will fill up the space of any container. Particles move quickly in all directions and bump into one another., Temperature, The average kinetic energy of the particles of a substance., thermal energy, total kinetic energy of all of the particles of a substance
