Matter & Measurement
Matter & Measurement Test
| Term | Definition |
|---|---|
| weight | a measurement of the gravitational pull on an object |
| mass | the amount of matter in an object |
| meniscus | bottom part of the curve of the liquid being measured |
| volume | amount of space an object takes up |
| density | the amount of matter within a particular space. |
| condensation | change from a gas to a liquid |
| graduated cylinder | tool used to measure volume of an irregular object |
| ruler | tool used to measure the volume of a regular object |
| Physical Properties of liquid water | density - 1.0 g/mL has a definite volume boils at 100 degrees C |
| Newtons | unit of measurement for weight |
| Spring Scale | tool used to measure weight |
| triple beam balance | tool used to measure the mass of an object |
| Formula for Measuring Volume | V = L x W x H |
| Formula for Measuring Density | D = MASS divided by VOLUME |
| Density of Water | 1.00 g/mL |
| Buoyancy | the upward force that keeps things afloat |
| Archimedes Principle | an object will float when the upward buoyant force is EQUAL TO the weight of the object |
| Objects will FLOAT | when their density is less than 1.00 g/mL (density of water) |
| Objects will SINK | when their density is more than 1.00g/mL (density of water) |
