100

anything that has mass and takes up space

Matter

100

Phase change where a liquid becomes a solid

Freezing

100

Properties that can only be observed when one substance changes into a different substance.

Chemical Property

100

Consists of only one kind of atom

Element

100

Oil and water do no mix.  Oil floats on water because it is less _____________.

Dense

200

Particles are tightly packed, vibrating about a fixed position

Solid

200

Phase change where a solid becomes a liquid

Melting

200

Any change that transforms one substance into a different substance

Chemical Change

200

The building blocks of matter.  Made of protons, neutrons, and electrons

Atom

200

Calculate the density of a metal that displaces 30 mL of water and weighs 60 g.

d = m / V

d = 60 g / 30 mL

d = 2 g/mL

300

Particles are very far apart and move freely

Gas

300

Phase change where a gas becomes a liquid

Condensation

300

Properties that you can measure or see through direct observation.

Physical Property

300

A mixture in which the parts of a mixture are very different from one another.

Heterogeneous

300

The tension of the surface film of a liquid caused by the attraction of the particles in the surface layer is

Surface Tension

400

Have definite shape and definite volume

Solids

400

Phase change where a liquid becomes a gas

Vaporization (boiling)

400

Changes in the physical properties of matter.  Can be reversed without changing one substance into another.

Physical Change

400

Two or more atoms of the same element.  Br2, I2, N2, Cl2, H2, O2, F2

Molecule

400

Hand sanitizer soap burning is an example of which kind of change?  Chemical Change or Physical Change?

Chemical Change

500

Has Indefinite Shape and Indefinite Volume

Gas or Plasma

500

Phase change where a solid becomes a gas

Sublimation

500

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

500

Atoms of two or more different elements bound together.  HCl, H2O, CO2

Compound
