Mass Lab Station #2

          I chose lab number two with the ice and water. My system was a test tube, ice cube, and a scale. The question was, would the mass change, and if so why, and are the particles the same? My answer to the first question is no the mass does not change. My answer to the second question is yes the particles are the same. Here's why, nothing in my system changed except that the ice melted, but since the amount of water and the amount of ice were the same, nothing changed. The mass is the same because if nothing in your system changes then the mass will be the same. The particles are the same because water and ice are the same thing only one is frozen, but they are both made out of H20 therefore the same particles. Nothing is added; nothing is subtracted. The mass just stayed at 2.37 and there was zero change.
          My ideas are supported by all of the others in class, which was proven at our board meeting. I at first predicted that it would be the same mass and particles due to the reasons above and I believe it even more after looking at all of the data from all of my classmates and others that are taking chemistry now. We all agreed that if there was any change it was due to others spilling some of the water. We also agreed that the reason why all our numbers don't add up exactly is due to some getting a larger piece or smaller piece of ice. There wasn't much of a control on that. Which helps explain the conversation of matter. Conversation of matter means that the mass will stay the same if the system stays the same. If the system changes then so will the mass.
             My histogram shows that almost everyone had no change in their experiment and that we got the same answer. Those who did not weren't off by much, they either had human error or they had a bigger piece of ice then most.
             In real life you can use this as away to understand the world around you better and be able to solve other problems that may come your way. It could also help in some job areas and in math.
