?The contact angle for water on clean glass is close to zero. Calculate the surface
Chapter 14, Problem E14C.2(a)(choose chapter or problem)
The contact angle for water on clean glass is close to zero. Calculate the surface tension of water at \(20^{\circ} \mathrm{C}\) given that at that temperature water climbs to a height of 4.96 cm in a clean glass capillary tube of internal radius 0.300 mm. The mass density of water at \(20^{\circ} \mathrm{C}\) is \(998.2 \mathrm{~kg} \mathrm{~m}^{-3}\).
