When water is condensed its density decreases.The density of ice is 0.917 g/cm³ whereas the density of water is 1.02 g/cm³.So ice floats on water.

ice have less mass per unit volume , and it is less dense then the water because when water solidify it becomes lighter , after solidifiying it becomes 9% less denser then its liquid state , and also ice freezes from top to botom that is why if we put water in ice tray to solidify it first freeze on the top , to test this after 15 minutes take the tray out and press it on center you will find that the top layer freezed but inside it there is still water .
hope this will help plz mark as best
