Gases are less dense than solids.
Yes, there are at least two: Iodine vapor (molar mass 254) and Radon gas (222, but not natural occurring) are heavier (and so more dense) than Mercury vapor (200 g/mol).
Helium and neon are less dense than air; argon, krypton, xenon and radon are denser than air.
Dense
Most (but not all) oil is less dense than water. That oil which is less dense than water will float. That oil which is denser than water will sink.
Gases are less dense than solids.
Neon, ammonia, methane, hydrogen, helium and water vapour are the best lifting gases and are all less denser than air.
Ice is less dense than water
No. The gas phase is generally less dense than the liquid phase.
A wooden block can be less dense than water.
Bubbles are comprised of gases, which have a lesser density than water. Since they are less dense, they get pushed up to the surface, and they rise, lighter than the liquid around them.
no
Oil IS already less dense than water.
Easy, put a fruit in water and if it floats it is less dense than water.
Yes, there are at least two: Iodine vapor (molar mass 254) and Radon gas (222, but not natural occurring) are heavier (and so more dense) than Mercury vapor (200 g/mol).
Yes. Anything that is less dense than water will float on water.
Helium and neon are less dense than air; argon, krypton, xenon and radon are denser than air.
