States of Matter and Changes

Matter is present in three states: solid, liquid, and gas. When heated or cooled, matter can transition between these states. For example, heating solid ice causes it to melt into liquid water, and further heating turns it into gaseous water vapor. This process illustrates that matter doesn't disappear but changes its state.
