Properties of matters and their measurements
Answers
Answer:
Physical properties are properties that can be measured or observed without changing the chemical nature of the substance. Some examples of physical properties are:
. color (intensive)
. density (intensive)
. volume (extensive)
. mass (extensive)
. boiling point (intensive): the temperature at..
which a substance boils
. melting point (intensive): the temperature at which a substance melts
Measurement of Matter
The first questions we must answer are: Is all evidence matter? What is matter? How do we classify and collect the matter that matters?
In chemistry as in most sciences, matter is defined as anything that has mass and takes up space. Matter can therefore be weighed and measured and the numbers generated analyzed and compared for the sake of evidence or research. When we measure the matter we will use, it is important to follow the rules of collection and computation that keep the measurements in a form that is capable of comparison. What I mean by this is that you can�t weigh an object on a scale capable of only measuring to the 0.1 gram but report it to the 0.001 gram. That would be claiming a degree of precision that does not exist in the measurement. The use of significant figure rules will keep us from making this kind of mistake. We also need to realize that some of the evidence we will collect both in research and in forensic investigation is not in fact matter. Observations, while not a type of matter are of considerable value when investigating. Observations fall under a type of data called qualitative data and are just as important as quantitative (measured or calculated) data.
