no it would not float because an object must be lower than 1.00g/ml to float on water
If an objects density level is above 1.00 g/ml will it float above water?

the water vapour reaches the cooler higher atmosphere and it condenses into tiny droplets that we see as clouds
what happens when low density warm air rise?
400
Because other objects have different densitys

The boiling point is the temperature at which liquid changes to gas.
Melting point the temperature at which a solid begins to liquefy
What is The melting point and the boiling point?

at sea level you have more than enough oxygen to breathe but when you are at 2700 meters the person will highly be having trouble breathing because of the air density
if you were standing at sea level and another person is at 2700 meters what is the difference he feels and that you feel??
