Problem 1.5

Is the separation method used in brewing a cup of coffee best described as distillation, filtration, or chromatography? [Section 1.3]

Step-by-Step Solution:

Step 1 of 5) Many properties of matter are quantitative, that is, associated with numbers. When a number represents a measured quantity, the units of that quantity must be specified. To say that the length of a pencil is 17.5 is meaningless. Expressing the number with its units, 17.5 centimeters (cm), properly specifies the length. The units used for scientific measurements are those of the metric system. The metric system, developed in France during the late eighteenth century, is used as the system of measurement in most countries. The United States has traditionally used the English system, although use of the metric system has become more common In 1960, an international agreement was reached specifying a particular choice of metric units for use in scientific measurements. These preferred units are called SI units, after the French Système International d’Unités. This system has seven base units from which all other units are derived (Table 1.3). In this chapter we will consider the base units for length, mass, and temperature. There is nothing mysterious about how scientists work. The first idea to keep in mind is that scientific knowledge is gained through observations of the natural world. A principal aim of the scientist is to organize these observations by identifying patterns and regularity, making measurements, and associating one set of observations with another. The next step is to ask why nature behaves in the manner we observe. To answer this question, the scientist constructs a model, known as a hypothesis, to explain the observations. Initially, the hypoth
