Examples of physical changes in the kitchen include boiling water (change in state from liquid to gas), dissolving sugar in coffee (solid to liquid without a chemical reaction), and mixing vinegar and baking soda to form bubbles (gas release without forming new chemical products). Other instances are chopping vegetables (altering shape and size but not their chemical structure), and freezing fruit juice (liquid to solid). These transformations highlight physical changes that do not result in new substances.
