The equation for capillary rise can be represented as
h=2Tcosθ/rρg
if the height of the capillary tube is less than the height calculated by this equation,the water comes up to the height of the capillary tube and stops there.then the value of θ (angle of contac) keeps changing untill the equation balances out.
ie. the meniscus of the liquid becomes more convex until it attains equilibrium
