WebFeb 13, 2024 · On part A, cohesion came in play because water was the only substance we used, so the water molecules attracted one another due to the cohesion property; which is when alike molecules attract. Surface tension formed the bump around the penny when the water molecules were attracting to each other. http://labsci.stanford.edu/images/Surface-Tension-TA.pdf

WebThere are two types of "stickiness" in this demonstration: cohesion and adhesion. The attraction between water molecules is called cohesion . The cohesive force that occurs … WebTo demonstrate cohesion, it is useful to show attraction using magnets. To demonstrate adhesion, it is useful to place droplets of liquids on a surface (i.e. desk). During the lab, the measurements (number of drops on a penny before spilling) may be affected by the cleanliness of the penny. WebTesting the Properties of Aqueous Activity 3: Koherence Will Cost They one Penny! The surface tension of water is produced by cohesion.

WebUse the language of cohesion, adhesion, polar and nonpolar in relation to each of the liquids. Describe any differences you observed in relation to the surface the liquids were touching. Recall the penny experiment from Activity 2 where you were able to observe the effects of adhesion and cohesion on water’s ability to pile on top of the penny. WebCohesion is the ability of water molecules to bind together; this experiment ties into cohesion because for the water to stay on the penny, they must bind together. Hypothesis: I believe that about 15 water droplets will fit onto a penny. A droplet of water is rather small and water droplets will bind together. pchs insurance verificationWebThere are two types of "stickiness" in this demonstration: cohesion and adhesion.
