Question
(a) How high will water rise in a glass capillary tube with a 0.500-mm radius? (b) How much gravitational potential energy does the water gain? (c) Discuss possible sources of this energy.
1. $2.97 \textrm{ cm}$
2. $1.70 \times 10^{-6} \textrm{ J}$
3. Work is done by the surface tension. This work causes the change in gravitational potential energy.
