A vertical capillary is brought in contact with the water surface. What amount of heat is liberated while the water rises along the capillary ? The wetting is assumed to be complete, the surface tension equals `alpha`.

A vertical capillary is brought in contact with the water surface (surface tension = T). The radius of the capillary is r and the contact angle theta = 0^(@) . The increase in potential energy of the water (density =rho ) is

The capillary rise in a tube of diameter 1mm when surface tension of water is 0.06 Nm^-1 is

To what height will water in a capillary of 0.8 mm diameter rise? Assume the contact angle to be zero. If the surface tension of water is 7×10 ^ −2 N/m

While measuring surface tension of water using capillary rise method, height of the lower meniscus from free surface of water is 3cm while inner radius of capillary tube is found to be 0.5cm . Then compute surface tension of water using this data. (Take contact angle between glass and water as 0^(@) and g=9.8lms^(-2) )

The surface tension for pure water in a capillary tube experiment is

During capillary rise of a liquid in a capillary tube, the surface of contact that remains constant is of

A glass capillary tube is held vertical and put into contact with the surface of water in a tank. It was observed that the liquid rises to the top of the tube before settling to an equilibrium height h_(0) in the tube. Assume that water perfectly wets glass and viscosity is small. Is the length of the capillary tube larger then 2h_(0) ?
