• Physical change: A change in which only the physical properties of any substance get changed is called a physical change.
• During a physical change, no new substance is formed.
• Making ice cream is a physical change because no chemical properties are altered.
• Non-periodic change: The changes that do not occur periodically at regular intervals are known as non-periodic changes.
• It is considered to be a non-periodic change because no specific time intervals are required for the change to occur.
• Irreversible change: The change which cannot be reversed even by changing conditions is said to be an irreversible change.
