Study Notes
Measurement Units
- The SI base unit for mass is the kilogram (kg).
Converting Units
- To convert meters to centimeters using dimensional analysis, multiply the number of meters by 100 cm/m.
Tools for Measurement
- A graduated cylinder is used to measure large volumes.
- A micropipette is used to measure small volumes in the lab.
Measurement Scales
- The appropriate scale for small length measurements is the millimeter (mm) or micrometer (μm) scale.
- For large masses, the kilogram (kg) unit is most appropriate.
Liquid Properties
- The curve at the top of a liquid in a container is called the meniscus.
Prefixes in the Metric System
- The correct prefix for 0.000001 in the metric (SI) system is micro (μ).
