| Term | Definition |
|---|---|
| 1.0 | What is water's approximate density? |
| Archimedes' Principle | States that the buoyant force is equal to the weight of the fluid displaced by an object. |
| Boiling point | the temperature at which a substance boils |
| bottom of the meniscus | Where do you look to take a volume reading of a liquid in a graduated cylinder? |
| buoyant force | the upward force on an object in a fluid exerted by the surrounding fluid |
| Chemical change | a change in matter that produces one or more new substances |
| Chemical properties | the characteristics of a substance that determine how it will react with other substances |
| Conductivity | the ability of an object to transfer heat or electricity to another object |
| density | the amount of matter in a volume |
| Flammability | a material's ability to burn in the presence of oxygen |
| Hardness | the resistance to indentation |
| Malleability | the ability of a substance to be hammered or beaten into thin sheets without shattering |
| mass | the amount of matter in a solid, liquid, or gas |
| Melting point | the temperature at which a substance changes from a solid to liquid |
| meniscus | Curved surface of liquid |
| negative buoyancy | The weight of the object is greater than the buoyant force, and the object sinks. |
| neutral buoyancy | The buoyant force and the weight of the object are equal, and the object will hover in the water. |
| Physical change | a change of matter from one form to another without a change in chemical properties |
| physical property | the characteristics of a substance that can be observed or measured without changing the substance |
| positive buoyancy | The buoyant force is greater than the weight of the object, and the object floats. |
| pressure | the force per unit of area applied on a surface of an object |
| Reactivity | the property that describes the likelihood of a substance combining chemically with other substances |
| Viscosity | the resistance to flow |
| volume | the amount of space something occupies |
| water displacement | What do you do to find the volume of an irregular solid? |
