Physical and Chemical Changes
- Physical Changes: These alterations regard both the states or appearances of matter as well as their inner chemical structure, but the chemical structure is untouched. Examples are such as conversion of state (melting, freezing) and morphing of shape and size (cutting, tearing).
- Chemical Changes: The chemical changes, which are reactions, are about creating new substances with a different chemical structure from the grounds of which they come into existence. This may consist of combustions, oxidations, and decomposition reactions.
Properties of Matter
Every matter has its own set of properties. Physical and chemical properties can be used to classify these properties. Physical properties are those that may be measured or observed without affecting the substance’s identity or composition. Physical properties include odor, colour, density, and so on. Chemical properties are those in which the substance undergoes a chemical change. Chemical properties include acidity, basicity, reactivity, and so on. The physical and chemical properties of matter and their measurements are discussed in detail below.
