hydrogen floats at room temperature because it has a density less than 1.
Helium is lighter than air. So it will float in air.
Sodium shouldn't sink in water at room temperature, because the density of sodium is less than the density of water. The density of sodium at room temperature is 0.968 g/cm3, whereas the density of water at room temperature is 0.998g/cm3. So technically, sodium should float in water, not sink.
For something to be able to float on water, it requires a density lower than water. Water at room temperature has a density of 1 kg / L or 1000 g / dm3Atomic number 43 is the element Technetium. At room temperature Tc has a density of 11 g / dm3.So yes, it will float on water.
The the object you speak of is in water at approximately room temperature, then anything with a density above about 1 will sink; anything below 1 will float and anything at very close will be suspended in the water. So, to answer your question, high density equals sinking.
it will float as long as it is not fully covered water.
does Arsenic float or sink
I have a marker which float in water.
Float
How can you make a chocolate float or sink
scoria will sink but pumice will float.
what make stuff sink or and float
They sink and they float it just depends on the almond.
