Study Notes
Measuring Mass
- Grams are the unit of measurement for the mass of a hamster.
- The mass of a hamster can be determined using a balance.
- A balance compares the mass of an object to a known mass.
Measuring Volume
- A graduated cylinder measures the volume of a liquid.
States of Matter
- Solids have a definite volume.
- Liquids have a definite volume.
Measuring Matter
- Volume is suggested as a better way to measure matter than mass.
- Mass is a measure of the amount of matter in an object.
Measuring Tools
- A balance can be used to measure the mass of objects through comparison.
Balance and Mass
- If both sides of a balance are equal, it indicates that the objects on either side have the same mass.
Defining Volume
- Volume is a measure of the amount of space an object occupies.
Calculating Density
- Density is calculated by dividing mass by volume: Density = Mass / Volume
