Melting of a solid to a liquid, or evaporation of a liquid to a gas. The physical state is changed but it is the same substance (though some substances do breakdown under heating, then it becomes chemical)

∙ 14y agoThere are several differences between a physical and chemical change in matter or substances.=A physical change in a substance doesn't change what the substance is. In a chemical change where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed.==Physical changes can be reversed, chemical changes cannot be reversed with the substance changed back without extraordinary means, if at all. For example, a cup of water can be frozen when cooled and then can be returned to a liquid form when heated.==If one decided to mix sugar into water to make sugar water, this would be a physical change as the water could be left out to evaporate and the sugar crystals would remain. However, if one made a recipe for a cake with flour, water, sugar and other ingredients and baked them together, it would take extraordinary means to separate the various ingredients out to their original form.=

∙ 12y agoAnything that is not a chemical change might be a physical change. An example of a a physical change would be cutting something. Although you might have two equal pieces now, they have the same chemical makeup, making them physically different, but chemically the same. Some other examples include boiling, freezing, melting, breaking, etc. a substance.
