Nitrous Oxide is heavier than air.
it is lighter than water.
Depends on the solute: alcohol in water is lighter, salt in water is heavier than water.
meson is heavier than electron but lighter than proton
hydrogen
No, aluminum is not heavier when it is corroded. Corrosion is a chemical reaction that occurs on the surface of metals, including aluminum, when exposed to moisture and oxygen. It forms a layer of aluminum oxide, which is actually lighter than aluminum itself.
it is lighter than water.
heavier because they are two different weights
no
Helium is lighter than air
carbon dioxide is heavier than oxygen therefore oxygen is lighter.
Depends on the solute: alcohol in water is lighter, salt in water is heavier than water.
LIGHTER
Just, simply, Lighter than Air Vehicles are lighter than air, so that makes them fly, and Heavier than air vehicles are heavier than air, but they use airfoils on the wings to fly.
meson is heavier than electron but lighter than proton
rhenium
hydrogen
Xenon is more than 4.5 times heavier than air.
