Web2.03 Properties of Water Lab Introduction Water is everywhere. It makes up about 3/4ths of the surface of the earth. It makes up 50-95% of the weight of living organisms. It is in the air we breathe, the sinks we use and in every cell of the body. Each molecule of water is made up of 2 hydrogen molecules and 1 oxygen molecule bonded together. Water is a polar … WebSurface tension is typically measured in dynes/cm, the force in dynes required to break a film of length 1 cm. Equivalently, it can be stated as surface energy in ergs per square centimeter. Water at 20°C has a …

Cohesion occurs when liquid molecules stick to each other. In the case of water molecules, cohesion is high because of hydrogen bonding between the molecules. Adhesion describes how well liquid molecules stick to surfaces. WebCohesion allows for the development of surface tension, the capacity of a substance to withstand being ruptured when placed under tension or stress. This is also why water forms droplets when placed on a dry surface rather than being flattened out by gravity. ckd パルスブローバルブ np1x
