Request Answer. Cold water will adhere to a glass container more than hot water, because I think the water molecules are moving around more slowly when they're cold and are therefore more able to stick to the glass than the faster moving hot ones. And Paul Tatman is completely justified in stating that the water strider would likely sink if all of its body weight were to be concentrated on one leg, or all four legs right next to one another (increasing the pressure), as opposed to it being spread out over four widly splayed legs (a greater area), if there are four legs in the above image that is. . 7 What are some examples of adhesion and cohesion?
