True. State changes, such as melting, boiling, freezing, or condensing, are physical properties because they do not change the chemical composition or identity of matter.
True.
State changes, such as melting, boiling, condensing, freezing, and sublimation, are physical changes that alter the form of a substance without changing its chemical composition. In other words, the molecules or atoms in a substance rearrange themselves, but their identities remain the same.
To determine whether state changes are a physical property, you can consider the definition of physical properties. Physical properties are characteristics that can be observed or measured without changing the substance's chemical composition. Since state changes do not alter the identity of matter and can be reversed by changing the conditions, they are considered physical properties.
