(a) Interpretation: If the pressure of a sample of gas is held constant, its volume, V, is directly proportional to the absolute temperature of the gas, T. An equation for the proportionality between V and T, in which b is the proportionality constant is to be stated. Concept introduction: Generally, proportionality is stated as two varying quantities having multiplicative connection with proportionality constant. When either of their ratio or their product yields a value, this value is called proportionality constant or coefficient of proportionality. The variable of y is related with another variable x via a proportionality constant c as y = c x . In other words, the value of proportionality constant c is given by y/x.
