Q. Figure s (a) and (b) show refraction of a ray in air incident at 60°with the normal to a glass Answer According to the given figure for the glass-air interface:
p1v1=p2v2 let partial pressure of helium in 30L be P then p1*30=2*10 p1=20/30 bar=2/3bar partial pressure of O2=p2 p1+p2=1bar partial pressure of O2=1/3 bar
p1v1=p2v2
let partial pressure of helium in 30L be P
then p1*30=2*10
p1=20/30 bar=2/3bar
partial pressure of O2=p2
p1+p2=1bar
partial pressure of O2=1/3 bar
