where \(γ\) is the surface tension, \(θ\) is the contact angle, \(ρ\) is the density of the liquid, \(g\) is the acceleration due to gravity, and \(r\) is the radius of the capillary tube.
where \(γ\) is the surface tension and \(r\) is the radius of the bubble. surface tension problems and solutions pdf
The pressure difference across the surface of a soap bubble is given by: where \(γ\) is the surface tension, \(θ\) is
The height of the liquid column in the capillary tube is given by: h = ( 1000 k g / m 3 ) ( 9
h = ρ g r 2 γ c o s ( θ )
where \(γ\) is the surface tension and \(θ\) is the contact angle.
h = ( 1000 k g / m 3 ) ( 9.8 m / s 2 ) ( 0.05 m ) 2 ( 0.03 N / m ) c o s ( 0° ) = 0.012 m
