Matter: 1 & 2 Assess
Matter Chapters 1 and 2 Assessment Review
| Question | Answer |
|---|---|
| What are some examples of General Properties | mass / dens / vol / length |
| Mass is measured in? | grams |
| As mass increases, what happens to inertia? | it also increases |
| Response of mass to the pull of gravity is | weight |
| Two units that measure volume are | mL / Cubic cm / CC's |
| Density = | m/v |
| Ice floats in liquid water because ice. | less dense |
| The density of water is | 1 g/mL |
| How does location change gravity? | closer to the center of earth the heavier you would be |
| Why does ice float? | it is less dense than water 1 g/mL |
| The constant amount of matter in an object determines its | Mass |
| Resistance of an object to change in its motion | Inertia |
| Examples of chemical changes and physical changes | burning / smoking / exploding |
| Solids have definite what? | shape and volume |
| Examples of physical properties are | mass / vol / dens/ color / shape / texture |
| These describes how a substance changes into other new substances | Chemical Properites |
| Resistance of the liquid to flow | Viscosity |
| When a substance changes from a solid to a gas without becoming a liquid | Sublimation |
| Changes in which no new kinds of matter are produced are what type of property | Physical |
| Particles of a gas can? | Expand without limit |
| The change of a substance from a gas to a liquid is called | Condensation |
| The change of a liquid to a solid is called | Freezing |
| How are tiny particles that make up a solid formed? | Packed Tightly |
| Give two examples of substances that sublime | Snow / Dry Ice |
| Mowing the lawn is an example of what type of change? | Physical |
| What has a definite volume, but not a definite shape? | Liquid |
| When a gas leaves the surface of a liquid, the liquid | evaporates |
| Particles of a liquid are | fairly close together |
| In Boyle’s law, if the pressure on a gas was 40units and that gas occupies a volume of 50units, what would the new volume be if the pressure were changed to 20units? | 100 units |
| In Charles’ law, if the temperature on a gas was 120o and this gas occupies a volume of 80units, what would the new volume be if the temperature was decreased to 60o? | 40 units |
| According to Boyle’s Law, when the pressure on a gas increases, the volume of that gas | Decreases |
| According to Charles' Law, when the temp on a gas increases, the volume of that gas | Increases |
| What are examples of Specific Properties | Color / texture / smell / |
