Study Notes
Measurement Units in the Metric System
- Milli (m) represents 0.001 or one-thousandth.
- Gram is the basic unit for mass in the metric system.
- Density is defined as mass divided by volume (p = m/V).
Significant Figures
- Nonzero digits are always significant.
- Zeros between significant figures are also significant.
- Zeros at the end of a number and to the right of the decimal point are significant.
- Leading zeros (before the first nonzero digit) are not significant.
Measurement Precision
- Precision indicates the scale or measurement device used for measurement.
Base Units in English and Metric Systems
- Slug is the base unit for mass in the English system.
- Gallon is the basic base English unit for measuring volume.
- Weight measures the pull of gravity on an object.
- Volume indicates how much space an object occupies.
- Gram is the metric unit for weight.
- Liter is the basic metric unit for volume.
Meniscus in Liquid Measurement
- The meniscus is the curve at the surface of a liquid in response to its container, and volume is measured at the center of this curve.
Mass Measurement
- Mass measures how much matter exists in an object.
Problem-Solving Methods
- Factor-label method involves listing units with numbers when solving problems.
- Significant figures and accurate representations are critical in scientific notation.
Graduated Cylinder Usage
- A graduated cylinder is a tool used by chemists to measure volume, resembling a rain gauge with markings (graduations) for measurement.
