Webnewton/meter 至erg/centimeter² (N/m—erg/cm²) 单位转换。 WebThe meniscus will have a convex form if the adhesion force between the liquid and the inner tube surface is lesser than the cohesion force between the liquid molecules. As an illustration, consider mercury, which is housed in a transparent tube. Similarly, a concave meniscus will result if adhesion is greater than cohesion.

WebMeasure the height of the meniscus in each tube from the bottom of the Petri dish. Record the height of the water in each of the tubes. Invent and record a hypothesis for any differences in water height or meniscus that you observed in the capillary tubes. Use the language of cohesion and adhesion in relation to the water and the tubes. WebCohesive forces hold the water molecules together and create surface tension, causing a meniscus ( a curved surface) to form. Because the atmospheric pressure under the …
