Core Concepts in Chemistry: Units and Measurement by 3G Editorial Board
Requirements: .PDF reader, 9.9 MB
Overview: In every area of science, measurements are taken, understood and connected together. In other terms, we all need to speak the same basic language. Whether you are a chemist, a physicist, a biologist, an engineer, or even a medical doctor, you need an unfailing style of communication to explore size, mass, shape, temperature, time, quantity, power, energy, and speed. It is important to be both precise and accurate when taking scientific measurements. Accuracy is how close the measurement is to its true value. This is important because poor equipment, poor data processing or human error can lead to incorrect results that are not approximate near to the reality. Precision is how close a number of measurements of the same thing are to each other. Measurements that are imprecise do not properly identify random errors and can yield widespread effects. It enables us to formulate our theories and to test our assumptions.
This book will try to explain the units of measurement and how important to chemistry is. This demonstrates the need for measurement: units of measurement; systems of units; SI units, fundamental and derived units. It will explore length, mass and time measurements; accuracy and precision of measuring instruments; errors in measurement; significant figures. You will learn skills including standardization, managing a metrology system, and units and instrumentation of measurements.
