| Question | Answer |
|---|---|
| matter | anything that has mass and takes up space |
| volume | the amount of space taken up |
| meniscus | the curve at the surface of a liquid |
| mass | the amount of matter in an object |
| weight | a measure of the gravitational force on an object |
| inertia | the tendency of an object to resist a change in motion |
| physical property | can be observed or measured without changing the matter's identity |
| density | the amount of matter in a given space |
| examples of physical properties | thermal conductivity, state, density, solubility, ductility, malleability |
| density equation | D = m/V |
| density label | g/cm3 |
| physical change | a change that affects one or more physical properties of a substance |
| chemical properties | describe matter based on its ability to change into new matter that has different properties |
| chemical change | happens when one or more substances are changed into new substances that have new and different properties |
| examples of chemical change | soured milk, rusting, mixing chemicals, digesting in your stomach, burning, fireworks, baking, temperature change, bubbles, tanning |
| characteristic property | a property that describes something |
| label for volume | cm3 |
| equation for volume | V = length * width * height |
