| Density describes the relationship between what? | mass and volume |
| Hardness measures a solids resistance to what? | scratching |
| What is the hardest natural substance on earth? | diamond |
| Elasticity is the measure of a solids ability to be what? | strectched and return to its original size |
| Brittleness measures a material's what? | tendency to shatter upon impact |
| Malleability measures a solids ability to what? | be pounded into thin sheets |
| Tensile strength is a measure of what? | how much pulling/tension a material withstands before breaking |
| Fluid | any matter that is able to flow |
| 3 properties of fluids | density, buoyancy, and viscosity |
| Buoyancy | measure of upward force fluid exerts on an object |
| Viscosity | materials resistance to flow |
| Archimede's Principle | the force exerted on an object in a liquid is equal to the weight of the fluid displaced |
| 3 fluids with high viscosity | syrup, ketchup, corn syrup |
| 3 fluids with low viscosity | coke, water, vinegar |
| Why are some liquids more viscous than others? | it depends on the shape of the molecules |
| Hardness | A measure of a solid's resistance to scratching |
| Calculating Density | Mass/Volume or mass divided by volume |
| Mass | measured in grams, calculated using an electronic balance, mass of an object stays the same as it goes through each phase change |
| Definition of mass | amount of matter |
| Definition of volume | amount of space matter occupies |
| Volume | measured in cubic cm or mL, can be calculated with a formula for some objects, displacement can help us find the volume of irregular shaped objects |
| Calculate volume | Length X Width X Height |
| Slowest Molecular Movement of water to Fastest Molecular Movement | Solid - Liquid - Gas |
| Evaporation | Fast-moving molecules in a liquid can escape to become a gas |
| Melting | Temperature at which water changes from a solid to a liquid |
| Freezing | Process of a liquid releasing thermal energy to a solid |
