1.) Explain your results from both parts of the experiment in terms of cohesion and surface tension.
1.) 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.
On part B, when soap was added to water the molecules didn't attract as much because it wasn't cohesion anymore. Then, the bump around the penny wasn't strong or big enough.
2.) How do your results compare to the other groups in your class?
2.) Our results were different from other groups, like some groups reached up to 50 or more drops . It all depends on how much force was used on the eyedroppers, on how quick or slow you were going, and if your hand was shaky or still.
