The first of these principles was Charles’s Law. This law explains that at constant pressure, the volume of a given mass is directly proportional to the temperature (in Kelvin). The equation used to explain is principle is V1/T1 = V2/T2. …show more content…
Absolute zero is the lowest possible temperature, where nothing could be colder and no heat energy remains in a substance. The absolute zero value of an experiment is the temperature at which entropy reaches its minimum value. The theoretical values for absolute zero is 0 Kelvin (-273.15 ◦C or -459.67 ◦F). This principle applies to the experiment as it explains the value at which a gas would theoretically have a volume of 0 mL and would therefore take up the least amount of space. Theoretically, if a person could get the temperature of propane to 0 Kelvin, the volume of this gas would be 0 …show more content…
In the first trial, the water was so cold that none of the group members could hold the balloon under the water and ice; hence, a pair of tongs was used. The tongs were very thin and it was hard to keep control of the balloon. In the second, third, and fourth trials, one of the group members was able to use his hand to submerge the balloon in the bucket of water. His hand was much larger than the tongs and it was easier to control the balloon. For the last experiment, because the water so was hot, the tongs had to be used to again to submerge the balloon. Again, the tongs were hard to use because the balloon was so large (the gas inside expanded in the warm temperature) and it keep popping up out of the water. Because two different methods were used, a different amount of water was displaced. Not only was the amount of water displaced by the balloon collected and recorded, the water displaced by the apparatus for submerging the balloon was collected and recorded. Using the group member’s hand probably displaced a lot more water than the tongs; this would cause variation in the data. Because the same apparatus wasn’t used for each method, the results aren’t as precise as they should be, causing discrepancy between the known absolute zero value and the experimental
