What's the Matter?
anything that has mass and takes up space
Matter
Phase change where heat leaves the liquid to form a solid
Freezing
Properties that can only be observed when one substance changes into a different substance.
Chemical Property
Consists of only one kind of atom
Element
These have Indefinite Shape and Definite Volume
Liquid
Particles are tightly packed, vibrating about a fixed position
Solid
Phase change where heat goes into the solid to form a liquid
Melting
Any change that transforms one substance into a different substance
Chemical Change
The building blocks of matter. Made of protons, neutrons, surrounded by a cloud of electrons
Atom
Phase change where heat goes into the solid to form a liquid
Melting
Particles are very far apart and move freely
Gas
Phase change where heat leaves the gas to form a liquid
Condensation
Properties that you can measure or see through direct observation.
Physical Property
A mixture in which the parts of a mixture are very different from one another.
Heterogeneous
The four phases or states of matter are
Solid, liquid, gas, plasma
Have definite shape and definite volume
Solids
Phase change where heat goes into the liquid to form a gas
Vaporization (boiling)
Changes in the physical properties of matter. Can be reversed without changing one substance into another.
Physical Change
Two or more atoms of the same element, or different elements, that are chemically bound together
Molecule
Matter is made up of particles that are in constant random motion
True
Has Indefinite Shape and Indefinite Volume
Gas or Plasma
Phase change where heat goes into the solid to form a gas
Sublimation
Release of Gas (bubbling); Formation of a precipitate (liquid turns cloudy); Release or absorption of energy (temperature change); Color change
Evidence of a Chemical Change or Chemical Reaction
Atoms of two or more different elements bound together
Compound
Phase change where heat leaves a gas to form a solid
Deposition
