Chemical changes are irreversible because substances mix and cause a reaction which creates a new substance. Chemical changes can be caused when a substance is combined with a heat‚ water or another substance. Heat can cause a chemical reaction called caramelisation which is when sugar is heated at a high temperature causing it to break down. This gives the sugar a nutty taste and causes it to brown. Physical changes are changes that change the physical appearance‚ smell and
