Solid- This state of matter for water is going to be denser than any other state of matter because the molecules are packed tighter together
Liquid- This state of matter for water is not going to be as dense as the solid form because the molecules can move around a little bit more freely than a solid
Gas- This is lighter than any other states of matter because the molecules have more room so they spread out and combine with other things in the air which makes them lighter
