(a) Interpretation: To write an equation that represents the direct proportion, in which D is the proportionality constant. Concept introduction: The scope of the measurement depends upon the context and event. Measurement is commonly used as an international system of unit as a comparison framework. Two variables such as mass (m) and volume (V) can be described as directly proportional one on other by the expression m α V. Besides, the term density is given by the mass of the given substance per unit volume. It is denoted by the symbol ‘D’.
