Cancel common units ex: g/cm2 and g it would be cm2
Term
Will a substance float in water if its density if less than 1?
Definition
Waters density is 1 so if a substances density is less than one it will float in water
Term
Will a substance float in water if its density if more than 1?
Definition
Waters density is 1 so if a substances density is less than one it will not float in water
