water drops on penny lab? | Yahoo Answers
QUESTION & ANSWERRELATED QUESTIONSQuestionWater drops on penny lab? ok. So i had to do a lab this week where we had to see how much distilled water,deterhent solution, sodium carbonate solution, and sodium chloride solution would fit on the surface of a penny. I used the same pAnswerIndependent variable: This is the one you're changing in the experiment, so it's the type of solution that you're dropping on the penny. Dependent variable: This is the one that you're measuring. In this case, it's how many drops you can get See more on answersoStatus: ResolvedPublished: Apr 10, 2008Answers: 3
Drops on a Penny | Science Experiments | Steve Spangler
The cohesion and surface tension of water becomes apparent when the drops of water you add to the penny reach the penny’s edge. Once the water has reached the edge, you begin to see a bubble or dome of water forming on top of the penny.

answers to penny surface tension lab Answers To Penny Surface Tension Lab by Parachute Publishing Answers To Penny Surface Tension Surface tension refers to the ability of a liquid to resist the force of gravity. For example, water forms droplets on a table because the water molecules at the surface group together against the force of gravity.

Surface Tension Surface tension is the name we give to the cohesion of water molecules at the surface of a body of water. The cohesion of water molecules forms a surface "film" or “skin.” Some substances may reduce the cohesive force of water, which will reduce the strength of the surface “skin”
Measure Surface Tension with a Penny - Scientific American
Jun 25, 2015In this activity you will see how soap decreases the surface tension of water by putting water droplets on top of a penny. Materials. Penny. Medicine dropper or eyedropper. Glass, cup or small bowl. Tap water. Dish soap. Dish towel or paper towel.Author: Science Buddies
Measuring Surface Tension of Water with a Penny
PREPARATIONMATERIALSPROCEDUREDATA SHEETAsk students if they have ever seen a water strider sitting on the surface of a pond. The water molecules stick together and form a “skin” on the surface strong enough to hold up the insect. This is an example of surface tension, the ability of a liquid to stick to itself. Surface tension may be affected by adding soap to the water, and the effect can be measured by comparing the number of drops of plain tap water versus the number of drops of soapy water that stick to a penny. If soap increa..See more on brighthubeducation
