The temperature at which a substance changes from a liquid to a gas.
The temperature at which a substance changes from solid to a liquid.
The ability to be pulled into a wire.

The ability the substance has to allow electricity to flow through it.
The ability to dissolve in another substance.
Color Transparency (ability to let light pass through) Odor Mass Volume Texture (smooth, slick, rough) State: (Solid, Liquid, Gas) Luster - Shiny or Dull Metal or Non-Metal elasticity (ability to stretch) Density
The amount of matter in a given volume FORMULA: D = M V
Formula: M = mass V= volume D = density MOVED M=massO=overV= volumeE=equalsD= denisty III. APPLICATION
Find the density : Set up your density problems like this: Use the Triangle Given: Mass = 35 gramsUnknown: Density (g/ cm 3 ) Volume = 7 cm 3 Formula: D = M / VSolution: D = 35g/7 cm 3 D = 5 g/cm 3 Ex. If the mass of an object is 35 grams and it takes up 7 cm 3 of space, calculate the density.
