yes they are
Gases are less dense than solids.
Helium and neon are less dense than air; argon, krypton, xenon and radon are denser than air.
You can put a uniform object into water.If it sinks density is higher than water,if floats lesser than water.If you can place anywhere in water,density is equal to water.
You can determine if a substance is more or less dense than water by comparing their densities. Water has a density of 1 g/cm3 at 4 degrees Celsius. If a substance has a density greater than 1 g/cm3, it is more dense than water. If it has a density less than 1 g/cm3, it is less dense than water.
Dense
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
A wooden block can be less dense than water.
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. Anything that is less dense than water will float on water.
Chlorine gas is less dense than water, so it will float on top of water if the two are in contact.
Alkanes are gases where water is a liquid. therefore the prior is less denser.
Water is less dense than any of the other materials listed.In order of density from least to highest:Water (least dense)GraniteBasaltIron (most dense)
No, the only planet in the solar system less dense than water is Saturn.
