What is the combined result of adhesion, cohesion, and surface tension? This is important because the ice provides a barrier in frozen lakes between the water at the bottom of the lake and the air. C. Electrons are evenly distributed in the water molecule. Adhesion is an attraction between molecules of different substances. One of water's most significant properties is that it takes a lot of energy to heat it. Subsequently, both of the hydrogen atoms take on a partial positive charge. Positive-negative attraction dictates how water behaves in some really important ways. Evaluate the following integral or state that they diverge. How is this possible?
