Question

When a small glass tube is placed in a beaker, the water climbs the glass without any outside force. This is due to which force?​

Answer 1

The primary one is the adhesion of the water to the glass surface causing it to climb up the surface. The other is the surface tension (i.e. the internal cohesive forces) of the water which assists the climbing and is responsible for the concave meniscus at the top surface of the water.
