![]() ![]() ![]() Once the chemical properties of a substance are changed, it becomes another substance. ![]() All chemical changes are irreversible changes. Chemical changes are changes that occur in the chemical properties of the substance like its flammability, radioactivity, etc.Like, turning of water into ice is an example of reversible changes but growth in height is an irreversible change. Physical changes may or may not be reversible changes. Physical changes are changes that occur in the physical properties of the substance, like shape, size, and nature.To understand reversible changes and irreversible changes better, we need to know what physical changes and chemical changes are. Most physical changes are reversible changes.Īll chemical changes are irreversible changes. The chemical properties of the substance change. The chemical properties of the substance do not change. (Source: ) Difference between reversible changes and irreversible changes Reversible changesĪ substance can return to its original state.Ī substance cannot return to its original state. When you cool this vapor down, it turns back to water.Ī change which cannot happen backward, that is, it cannot be reversed is called an irreversible change. When you burn a piece of paper, it turns to ash. Similarly, if you boil water, it evaporates and becomes water vapor. But as soon as you take it out of the freezer, it turns into water again. If you keep water in the freezer for some time, it transforms into ice. A change which can happen backward, that is, can be reversed is called a reversible change. Reversible changes and Irreversible changesĪll changes in the world are one of the two types – Reversible changes and irreversible changes. ![]()
