Van der Waals gases such as methane, however, have weak cohesion due only to van der Waals forces that operate by induced polarity in non-polar molecules. Cohesion, along with adhesion (attraction between unlike molecules), helps explain phenomena such as meniscus, surface tension, and capillary action.
