The measurement of the boiling point of water does not change its identity or composition. The fertilizer is consumed by the growing plants it is turned into vegetable matter (different composition). Oxygen gas is consumed in a combustion reaction its composition and identity are changed. 1.4 (a) hypothesis (b) law (c) theory 1.11 (a) Chemical property. Even though numbers are involved, they are not the result of measurement. If the numerical values for the densities of ice and water were given, it would be a quantitative statement.
