The proportion of water molecules that have gained a hydrogen atom (H 3 OR + ) To water molecules that have lost a hydrogen atom (OH - ). A multimeter and temperature sensor are used, respectively. If it is electricity it is measured in Ohms and if it is by heat it is measured in Watts per meter Kelvin (W / m K). ConductivityĬonductivity ability of a substance to conduct electricity or heat. And the method of marked volumes is used. It is measured in grams on cubic centimeters (g / cm 3 ) Or grams on milliliters (g / mL) or grams on liters (g / L), etc. The density of water is 1.0 g / ml, and is often the reference for the other substances. DensityĪmount of mass in a given volume of a substance. The measuring instrument is the thermometer. It is measured in degrees centigrade (° C) or degrees Fahrenheit (° F). Temperature at which the change from a liquid state to a gaseous state occurs. Temperature at which the change from solid state to liquid state occurs. It is the kinetic energy (movement) of particles in a substance, measured in degrees centigrade (° C) or degrees Fahrenheit (° F) with a thermometer. It is a measure of the warmth of a substance with reference to a standard value. Examples of quantitative properties of matter Temperature Often quantitative properties are unique to a particular element or compound, in addition the registered values are available as a reference (can be searched in tables or graphs).Īny quantitative property involves a number and a corresponding unit, in addition to an associated instrument that allows measuring it. Oppositely, the quantitative physical properties of matter are those that can be measured and assigned a particular value. To understand the term quantitative, it is necessary to understand that its opposite, the qualitative properties, are those that can be observed through the senses: sight, sound, smell, touch Without making measurements, such as color, smell, taste, texture, ductility, malleability, clarity, luster, homogeneity and state. In contrast, qualitative information records descriptive, subjective, or difficult to measure qualities.
The word quantitative refers to information or quantitative data that are based on quantities obtained through a quantifiable measurement process, ie any objective basis of measurement.
