Chapter 1: Properties of Matter

1/29/2016

What is Matter?Matter: anything that has volume and mass.

Matter: anything that has volume and massVolume: the amount of space that something occupies or the amount of space that

something contains.

Measuring the Volume of LiquidsMeasure liquids from the bottom of the meniscus: the curve at a liquid’s surface.

Units: Liters (L), milliliters (mL)

Measuring the Volume of SolidsThe volume of solid objects is expressed in cubic units.

Ex) m3

, cm

3

Solid objects have three dimensions!

Matter: anything that has volume and massMass: the amount of matter that something is made of.

Physical PropertiesA Physical Property can be observed or measured without changing the identity

of an object.

Physical PropertiesDensity: a comparison of the mass and volume of objects.

Physical PropertiesMalleability: the ability to flatten into a thin sheet.

Physical PropertiesDuctility: the ability to be drawn into a thin wire.

Physical PropertiesThermal Conductivity: the ability to move or carry heat.

Physical PropertiesSolubility: the ability to dissolve in another substance.

Oil is NOT

soluble in

water.

Physical PropertiesViscosity: a liquid’s resistance to flow.

High Viscosity=thick, resists flowing Low Viscosity=flows easily

Chemical PropertiesChemical Properties describe an object’s ability to change into a new, different

substance.

Chemical PropertiesFlammability: the ability to burn.

Chemical PropertiesReactivity: the ability to chemically react with another substance.

Physical ChangePhysical Change: a change that affects one or more physical properties of a

substance.

Many physical changes are easy to undo.

Chemical ChangeChemical Change: a change that occurs when one or more substances are

changed into entirely new substances with different properties.

Chemical changes cannot be reversed using physical means (cannot uncrumple or iron

out a chemical change); difficult to undo.
