If we insert a capillary tube into a liquid which has a contact angle of $110.$ Will the

liquid level in the capillary be higher or lower than the level of the rest of the liquid?

Explain.

$($Optional$)$ Water can be carried to the upper parts of trees by tiny tubes partially because

of the capillary effect. In a tree with $2\mathrm{.}5-m-$diameter tubes, how high the water can rise

along the tubes as a result of the capillary effect? The contact angle between water and

tube wall is $15.$
