Final answer:
Materials selection involves choosing appropriate materials for specific applications, considering properties and performance. Scientists consider factors such as surface chemistry in sampling plans for accurate analysis. Sampling errors are crucial to consider when working with heterogeneous materials.
Explanation:
Materials selection is the process of choosing suitable materials for a specific application. This involves analyzing properties, characteristics, and performance of materials to ensure they meet the requirements of the intended use.
For example, in designing a Sampling Plan (7.2), material scientists consider factors like surface chemistry when selecting samples for analysis to achieve accurate results.
Sampling errors are important to be aware of when dealing with heterogeneous materials as they can affect the representativeness of samples and subsequently the results of analyses.
