Paragraph in three measurements means that all 21. Good accuracy and good precision the true value three have what in common other and close to A) Values close to each Values close to each other to each other Values close to the true value necessarily close D) Values to the true value, but not close 24. What two measurements determine density, and in what relationship to each other? by mass A) Volume multiplied B) Mass by volume Mass divided by volume D) Volume divided by mass at a 26. What simple property is used to identify glass and match it to glass crime scene? A) Density B) Mass C) Volume. D) Weight. 27. Glass density is often measured by the sink-float method. B) False 28. is the density gradient method used to analyze soil density lower in A) The soil is placed in a cylinder of solution with increasing the cylinder, and it is measured where is aligns with the solution. The soil is placed in a cylinder of solution with decreasing density lower in the cylinder, and it is measured where is aligns with the solutidn C) The soil sample is measured against the density of several known soil samples. D) The density gradient method is not used to measure the density of soils and solids.Explanation / Answer
21)
Accuracy is closeness of measured value to true result
Precision is closeness of measured value to each other
Answer: A
24)
density is defined as mass / volume
Answer: C
26)
glass is of less density
