Surface tension lab report - Free download as PDF File (.pdf), Text File (.txt) or read online for free. Cohesion is the attraction of like molecules to one another. Surface tension refers to water's ability to "stick to itself". Surface tension is the force that holds atoms or molecules of the same substance together when they are in contact with another substance. This is the basis of “capillary” It is the reason that water collects in drops, but it’s also why plant stems can “drink water,” and cells can receive water through the smallest blood vessels. View Surface tension lab report.docx from CHEMISTRY 325 at Middlesex County College. In this case, the like molecules are the H20 molecules in the water drops. First, the lower surface tension means that the paper can’t sit atop the water’s surface, allowing more of the water to come in contact with more of the paper. 1. (1) is equilibrated by the mass of the liquid raised in the capillary to the height h, that is the gravity force f 2.In the case of non-wetting liquid – it is lowered to a distance –h. Surface Tension Experiments. Surface Tension of Water Lab Testable Question: Results Averages 0.0304 mL per drop Avg Drop Volume w/ Pure Water Avg Drop Volume w/ 25.00 mL Bleach By Aaron, Isabella, Cameron, and Leta What happens to surface tension of water when we add chlorine bleach? Here, the water molecules in the droplet are held together by surface tension while they are in contact with the desk. Due to their amphiphilic nature, these surface-active molecules facilitate the production of foam, emulsions and dispersions. Champagne Period 8 5/6/19 Lab Report Purpose: to observe an unusual surface property of water that You can test multiple surface tension experiments using just a few household items. Surface tension is one of the most important properties of water. Some things can affect the surface tension, like pollutants in the water. This lab focuses on two big ideas – Scientific Processes and Surface Tension. (2) where: d – the liquid density (g/cm 3) (actually the difference between the liquid and the gas densities), g – the acceleration of gravity. The surface tension can also be determined by the rise of liquid in glass capillary if attractive forces exist between glass material and liquid (e.g. Other examples of surface tension include water striders, dew drops, raindrops on a Take one 250mL Surface tension is a special term we use to describe the cohesion between water molecules. Surface Tension My problem was to find out how to test or measure surface tension.I think the reason of some of the force in surface tension is cohesion and gravity.Surface Tension is the condition existing at the free surface of a liquid, resembling the properties of an elastic skin under tension.The tension is the result of intermolecular forces exerting an … measuring surface tension using a tensiometer for 1-butanol to examine the dependence of surface tension on the molecules chain length Abdul Momoh Ms. DATE OF EXPEREMEN'| ':23‘ /10/2013 MANE OF STUDENT: Kamal Rahman Ahmad Group: C Mr. A|i SUPEVISED BY: 2. introduction The surface tension is an expression of the resistance which … Second, the weakened hydrogen bonds mean that the water is more likely to soak into the porous paper, making the paper much more dense and causing it to sink. Surface Tension Report 1. It is a result of the COHESION of water molecules. The force f 1 in Eq. (Part one: water surface tension) 1- Place the penny in a flat area 2- Fill a dropper with water 3- One by one add the drops of water to the top of the penny 4- Measure how many drops fit until the drops break the surface tension of the water.
