Everything that has mass and volume is called matter What is matter? Everything that has mass and volume is called matter It cannot be created or destroyed
Kinetic Molecular Theory all matter is made up of small particles that are always in motion. The kinetic energy (speed) of these particles increases as temperature increases.
Phases of Matter Solid Liquid Gas Plasma
Solids- (s) Kinetic Molecular Theory very low KE - particles vibrate but can’t move around fixed shape fixed volume Kinetic Molecular Theory Molecules are held close together and there is very little movement between them.
Kinetic Molecular Theory: Liquids-(l) low KE - particles can move around but are still close together variable shape fixed volume Kinetic Molecular Theory: Atoms and molecules have more space between them than a solid does, but less than a gas (ie. It is more “fluid”.)
Kinetic Molecular Theory: Gases-(g) high KE - particles can separate and move throughout container variable shape variable volume Kinetic Molecular Theory: Molecules are moving in random patterns with varying amounts of distance between the particles.
