Explain why the boiling point of water is a characteristic physical property but the temperature and the volume of a glass of water are not?

The boiling point of water is a characteristic physical property because it is a specific temperature at which water transitions from a liquid to a gas, and it remains consistent regardless of the amount of water present. In contrast, the temperature and volume of a glass of water can vary depending on external conditions, such as heat applied or the size of the glass, making them non-definitive for water itself. Thus, boiling point is intrinsic to the substance, while temperature and volume are extrinsic and dependent on the context.
