While the temperature and pressure a substance is under changes its density, it would take very high temperature and very low pressure on water and very low temperature and very high pressure on the hydrogen to make hydrogen more dense than water. So short answer, Hydrogen is less dense than water.

Which is more dense: water or helium? - Water is more dense, because water does not float like helium does. It is below air. That's why we have oceans and lakes and rivers.
No. Several liquids, including gasoline, oil and alcohol, are less dense.
Helium is a gas that is less dense than air. This is why a balloon filled with helium rises when released.
Helium is lighter (less dense) than oxygen & nitrogen.
Ice Air is less dense than water, so water sinks below air. A rock is more dense than water, so it sinks in water and air. And helium, which is less dense than air, rises in air and in water.
Yes, it is true.

No. Several liquids, including gasoline, oil and alcohol, are less dense.
Helium gas is less dense than air, so it will rise and float in both air and water.

Floating and sinking is related to density - if something is more dense (i.e. has more mass per volume) than the fluid it will sink, and if it is less dense then it will float. This is why wood floats in water, and helium balloons float in air - helium is less dense than air and wood is less dense than water. Steel ships float because, although they are made of steel which is more dense than water, the air inside them is less dense than water so the overall effect is floating.
Ice Air is less dense than water, so water sinks below air. A rock is more dense than water, so it sinks in water and air. And helium, which is less dense than air, rises in air and in water.
Yes. Helium is lighter than air.
Better check on that again, helium is lighter than air and the specific gravity of air is approximately 1.3 milligrams per cubic centimeter. Water weighs much more than air, 1 gram per cubic centimeter.
