| Question | Answer |
|---|---|
| General Properties of Matter | mass / density / volume / weight |
| mass can be measured in units called | grams |
| as mass increases what happens to inertia | it increases |
| weight is | the response of mass to the pull of gravity |
| unit used to measure volume | mL / cubic centimeter |
| Density = | m/v |
| Why does ice float in water | it's less dense |
| the density of water = | 1 g/ml |
| where would you weigh the most, on the moon, outer space, or the earth's surface? | earths surface |
| an object that floats has a density less than | 1 g/mL |
| the constant amount of matter in an object determines its | mass |
| the resistance of an object to a change in its motion | inertia |
| burning paper is an example of what type of change | chemical change |
| have a definite shape and volume | solids |
| mass,weight,color,shape,texture, hardness,volume,and density are all what type of property | physical property |
| all changes in phases are | physical changes |
| chemical properties describe how a substance can | change into another substance |
| resistance of the liquid to flow is | viscosity |
| changing from a solid to a gas | Sublimation |
| change in which NO new kinds of matter are produced | physical changes |
| particles from what phase are able to expand without any limit | gases |
| changing from a gas to a liquid | condensation |
| changing from a liquid to a solid | freezing |
| when tiny particles are packed tightly together they make up a | solid |
| example of a substance that sublimes | dry ice / snow |
| very high energy PHASE of matter not naturally found on earth | plasma |
| cutting your grass is an example of what type of change | physical |
| definite volume but no definite shape | liquid |
| Boyle's Law states , when the pressure on a gas increases the volume will | decrease |
| When gas leaves the surface of a liquid, the liquid | evaporates |
| particles of a liquid are | fairly close together |
