Explain how the law of conservation of mass is at work during physical changes such as size changes, state changes, or when substances are dissolved in another liquid

The law of conservation of mass states that mass cannot be created or destroyed only transfered. So when a size change takes place the mass is being transfered into something else. During a state change the mass is being transfered into another state of matter. When a substance dissolves into another liquid the mass is still their just into another state.
