Table 5. Relationship with the bubble diameter and the pressure in the bubble.

Diameter of bubble	Pressure in the bubble in water
1 mm	1.003 atm
100 μm	1.03 atm
10 μm	1.29 atm
1 μm	3.9 atm
500 nm	5.8 atm
300 nm	9.7 atm
200 nm	14.6 atm
100 nm	29.7 atm

Young-Laplace equation is as follows: ΔP = 4σ/d

ΔP: Degree of the upward pressure [atm], σ: Surface tension [mN/m], d: Diameter of bubble [mm].
