To determine which of the options listed is not a physical property of sucrose, let’s examine each option:
- a) It tastes sweet: This is a sensory property, but it’s not a physical property. Taste is more related to the chemical interactions of sucrose with our taste buds.
- b) It forms a solid white crystal: This describes the physical characteristics of sucrose. It indeed crystallizes into solid white structures, making this a physical property.
- c) It dissolves easily in warm water: This is also a physical characteristic of sucrose, describing how it interacts with water, which is a typical behavior of many solids.
- d) It becomes carbon dioxide and water when heated: This statement refers to the chemical change that occurs when sucrose is subjected to heat, leading to its decomposition rather than describing a physical property.
Thus, the correct answer is d) it becomes carbon dioxide and water when heated. This option describes a chemical change, not a physical property.
