Water is a common substance that undergoes both chemical and physical changes. Physical changes can include changes in state, such as melting or freezing, while chemical changes involve the formation of new substances through a chemical reaction, such as rusting or burning.
When water is evaporated this is a physical change; when water react with sodium this is a chemical change.
Reactivity is a chemical property, not a physical change. It refers to the ability of a substance to undergo a chemical reaction with another substance. Physical changes involve alterations in the form or state of a substance without changing its chemical composition.
When a substance is heated, it may undergo physical or chemical changes such as melting, evaporation, sublimation, or decomposition. These changes can result in alterations in the substance's physical state, color, texture, or chemical composition.
Yes, an object can undergo both physical and chemical changes. Physical changes involve changes in physical properties like shape, size, or state of matter without altering the composition. Chemical changes involve a transformation at the molecular level, resulting in the formation of new substances.
A chemical property of a substance refers to its ability to undergo a chemical change or reaction to form new substances. This property is related to the substance's composition and arrangement of atoms. Examples of chemical properties include reactivity with other substances, flammability, and acidity or basicity.
"Very reactive" is a chemical property because it describes how likely a substance is to undergo a chemical reaction with other substances. It does not pertain to any physical characteristic of the substance.
