Answer:
Its density decreases
Its volume increases
Explanation:
You notice that ice floats on water, this means that its density is less. The mass remains the same because you did not add or remove anything. But what causes the density to decrease then? For density to change, there needs to be a change in either the volume or the mass of the object. Density is calculate by mass/volume. Since the mass did not change, the volume must have. So in this case, the volume increases. Hence, this is what causes it to be less dense. :)
<span>Deuterium itself is not on the periodic table, but it is known as a heavy hydrogen which is on the table. The nucleus of deuterium is called deuteron and has a neutron in it while most commonly protium has no neutrons in its nucleus. Deuterium is one of two different stable isotopes of hydrogen. I'm not entirely sure on what answer you needed, but I hope this helped:)
