Study Notes
- Density is how tightly packed or heavy molecules are in an object.
- Density is measured in kilograms per cubic meter or grams per centimeter cubed.
- The differences in density between solids, liquids, and gases relates to the spacing between the particles.
- Mass is the measure of the amount of matter in an object, measured in grams.
- Volume is the measurement of the amount of space an object occupies.
- Volume is measured in milliliters or centimeters cubed.
- To determine an object's density, you need to know its mass and volume.
