chapter 3

1. a temperature scale that defines the freezing point of water as 0 degrees and the boiling point of water as 100 degrees
5. analysis using the fact that physical quantities added to or equated with each other must be expressed in terms of the same fundamental quantities such as mass, length, or time
9. a measure of how close a measurement comes to the actual value of whatever is measured
10. scale of temperature with absolute zero as zero, and the triple point of water as exactly 273.16 degrees
11. the lowest possible temperature, at which point the atoms of a substance transmit no thermal energy - they are completely at rest
12. an arithmetical multiplier for converting a quantity expressed in one set of units into an equivalent expressed in another
14. value the value of a substance's properties found in a localized lab

2. digits that carry meaning contributing to its precision. This includes all digits except All leading zeros Trailing zeros when they are merely placeholders to indicate the scale of the number
3. The difference between Approximate and Exact Values
4. the SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves one meter in the direction of action of the force
6. discrepancy between a computed, observed, or measured value or condition and the true, specified, or theoretically correct value or condition
7. a given number written as the product of two numbers a coefficient and 10 raised to power
8. the correct value based on reliable refrences
13. a measure of how close a series of measurements are to one
