Which of the following statement is not true about angle of contact?

A liquid is to be kept in a vessel and this brings the liquid in contact with some solid surface. For a liquid and solid, it is defined as the angle between the tangent to the liquid surface drawn at the point of contact with the container and the solid surface inside the liquid. The angle of contact does not depend on the inclination at which the liquid touches the container. The rise in temperature increases angle of contact. The addition of soluble impurities increases the angle of contact.

The angle of contact lies between
