Detailed explanation-1: -Water boils at 100 ° C and at this point, there will be a change of state from liquid gas. The volume occupied by the matters can change and no new substance is formed. That means when the water boils there will be only physical change no chemical changes occurs. Therefore, Water boiling is a physical property.

Detailed explanation-2: -Boiling point only changes the physical appearance of the substance without changing its chemical structure or molecular composition. For example, the boiling point of water changes water from a liquid phase to water vapor, which is a gas phase.

Detailed explanation-3: -Physical properties of water are related to the appearance of water, namely, the color, temperature, turbidity, taste, and odor.

Detailed explanation-4: -A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.

Detailed explanation-5: -The water must reach 100 degrees Celsius in order for the water to start boiling. So the boiling point is an intensive property. Likewise, melting point is also an intensive property. Other examples of intensive properties include density, solubility, color, luster, freezing point and malleability.
