with relative error.The uncertainty in a measurement, expressed with appropriate units. For example, if three replicate weights for an object are 1.00 g, 1.05 g, and 0.95 g, the absolute error can be expressed as ± 0.05 g. Absolute error is also used to express inaccuracies; for example, if

the "true value" is 1.11 g and the measured value is 1.00 examples of systematic errors in chemistry lab g, the absolute error could be written as 1.00 g - 1.11 g = -0.11 g. Note that when absolute instrumental error examples errors are associated with indeterminate errors, they are preceded with "±"; when they are associated with determinate errors, they are preceded by their sign. absolute temperature. Temperature measured on a scale that

sets absolute zero as zero. In the SI system, the kelvin scale is used to measure absolute temperature. absolute zero. (0 K) The temperature at which the volume of an ideal gas becomes zero; a theoretical coldest temperature that can be approached but never reached. Absolute zero is zero on the Kelvin scale, -273.15°C on the Celsius scale, and -459.67°F on the Fahrenheit scale. accuracy.
Classification Of Errors In Analytical Chemistry
Compare with precision and trueness.Accuracy is the correctness of a single measurement. The accuracy of a measurement is assessed by comparing the measurement with the true or accepted value, based on evidence independent of the measurement. The closeness of an average to a true value is referred to as "trueness". ampere. (A) amp.The SI unit of electric current, equal to flow of 1 coulomb of charge per second. An ampere is the amount of current necessary to produce a force of 0.2 micronewtons per meter between two arbitrarily long, arbitrarily thin wires, placed parallel in a vacuum and exactly 1 m apart. Named for 19th century physicist André Marie Ampère. Angstrom. (Å) Ångstrom; Ångstrom units.A non-SI unit of length used to express wavelengths of light, bond lengths, and molecular sizes. 1 Å = 10-10 m = 10-8 cm. atto-. (a) Prefix used in the SI system meaning "multiply by 10-18". For example, 3 am means 3× 10-18 meters. base unit. Base units are units that are fundamental building blocks in a system of measurement. There are seven base units in the SI system. calibration. Calibration is correcting a measuring instrument by measuri
