Answer: for an object or gas or liquid to float in another there must be a difference in density
Explanation:
Helium has a density of 0.18 kg/m³ and air has a density of 1.29 kg/m^³. If a balloon is filled with helium it will float in air due to density differences
Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces
It's not chemical because it would have to react to something to change so it is physical change because it is the same thing but it just smells I hope this helped

Explanation:
beginner because it's tough than other things
The dew point would be about 22 . (this is C )
This problem can be solved using Boyle's law:p1v1=p2v2
so 5.23*214=796*v2 v2=(5.23*214)/796=1.4L
