Water can exist in three states of matter. Imagine examining the changes of state from solid to liquid to gas by adding to ice. What would change or not change? As water changes state, the mass of the sample The size of the water molecules However, the of the water molecules does change during a change in state. The evidence that supports this conclusion is that the volume of the sample changes. kinetic energy
