| Question | Answer |
|---|---|
| What has mass and takes up space? | Matter |
| What does one call the amount of space taken by matter? | Volume |
| What is the curve at the surface of a liquid called? | Meniscus |
| What metric units are used for measuring volume of a liquid? | Liters and milliliters |
| What metric units are used for measuring mass? | grams and kilograms |
| How does one find the volume of a solid like a brick? | length X width X height |
| How might one find the volume of an object with an odd shape? | water-displacement method |
| What is a measurement of the pull of gravity on an object? | weight |
| What never changes no matter where an object is in the universe. | mass |
| What about an object will change based on its position in the universe? | weight |
| What is an object's tendency to either remain at rest or remain in motion unless acted upon by another force? | inertia |
| What determines the amount of inertia in an object? | mass |
| What are those characteristics of matter that can be observed or measured without changing the matter? | physical properties |
| What are some examples of physical properties? | odor, size, shape, volume, density, color, texture, etc. |
| The ability of a substance to transfer heat: | thermal conductivity |
| The physical form of matter: | state |
| The three states of matter: | solid, liquid, gas |
| The ratio of mass to volume in a substance: | density |
| The formula for calculating density: | D=M/V |
| The ability to dissolve in a substance: | solubility |
| The ability to be pulled into thin wire: | ductility |
| The ability to be hammered thin: | malleability |
| Although a golf ball and pin-pong ball have similar sizes, why does the golf ball have more mass? | its density is greater |
| What happens if an object or substance has a lower density than water? | it floats |
| What is it called when a change is made to an object or substance without changing the identity of the matter? | physical change |
| Cutting, tearing, crushing, freezing, melting, and dissolving are all types of: | physical changes |
| What about matter determines whether is has the ability to change into matter with a new identity? | chemical properties |
| Flammability and reactivity are examples of: | chemical properties |
| Those properties that are unique to matter and are used to identify matter are called: | characteristic properties |
| What are some really good characteristic properties of matter? | density, reactivity, flammability |
| This happens when one or more substances react with one or more other substances to form a new substance: | chemical change |
| Bubbling, light, odor, and sound are all pretty reliable signs that what has occurred? | chemical change |
| The specific number and arrangement of matter in a substance is called: | composition |
| The best way to tell if a chemical change has occurred to matter is to look at its: | composition |
| Of physical and chemical changes, which are more easily reversed? | physical |
