Matter:anything that has mass & takes up space
Atom:building blocks of matter, smallest particle of an element that still retains the properties of the element (chpt 17)
Compound:two or more elements combined (chpt 15)
Heterogeneous mixture:different materials combined but unevenly distributed (chpt 15)
Homogeneous mixture:two or more substances blended evenly throughout (chpt 15)
Pure substance:cannot be separated or can only be separated by a chemical process (chpt 15)
Mass:amount of matter in an object (chpt 1)
Volume:amount of space occupied by an object (chpt 1)
Density:mass ÷ volume (chpt 1)
Physical change:change in size, shape, or state of matter in which the identity of the substance stays the same (chpt 15)
Chemical change:change of one substance to another (chpt 15)
Law of Conservation of Mass:matter can neither be created nor destroyed (chpt 15)
Kinetic theory:all matter is made of constantly moving particles that collide (chpt 16)
Solid:particles are closely packed together (chpt 16)
Liquid:particles can slide past one another, takes the shape of their container (chpt 16)
Gas:particles are moving fast, fills whatever container it’s in (chpt 16)
Plasma:most common form of matter, consisting of positively and negatively charged particles (chpt 16)
Viscosity:a fluid’s resistance to flow (chpt 16)
Boiling point:the temperature at which liquid changes to gas (chpt 16)
Thermal energy:heat energy of moving molecules (chpt 16)
Element:pure substance, all atoms are alike (chpt 15)
