Water on a Clean, Dry Penny Trails are given below: Trial Number of drops 1 19 2 16 3 15 4 19 5 24 Observation: The cohesion and surface tension of water became apparent when the drops of water added to the penny reached the penny's edge. Once the water had reached the edge, began to see a bubble of water forming on top of the penny until it overflowed.

Questions:
1. Describe two things that affected your precision. Remember that Accuracy refers to how close measurements are to the "true" value, while precision refers to how close measurements are to each other.
2. In your own words, give a description of surface tension.
