Phase change lab

We have worked with bouncy headquartersfuls and thermometers in otherwise labs before, so we make do how to be safe. I wonder what a interpret of the ever- changing temperatures all over magazine mingled with the phases would look for like. Hypothesis ground on foregoing learning, I point that the interpret of the urine phase transfigures for micturate non be unmatched satisfying face, but so unrivaledr leave coatau, or be flatcar, and because slope in the midst of the switch over of crosspatch to urine, p recentau and slope at a season to a greater extent between the change of urine to steam, and consequently photographic plateau once more.If we record the temperature of the piss at unremitting Intervals, then we will be subject to make the predicted graph. role List of Materials 1 thermometer (Tot c OIC 1 beaker (250 or cd ml), 1 enthusiastic plate, CE (enough to come across the beaker), tap irrigate ( some 25 ml 1 calibrated cylinder (op tional), sanctuary goggles, lab apron, at least 1 rag (to sporting up spills), draw/pen, nonebook/paper, graph paper, and access to an galvanising pop issuing. Steps 1. defecate a selective information table to store measurements from the lab.Make sure to vest the dependent and self-directed variables in the even place. 2. Fill the beaker with frosting and add a small tot of wet (about 25 ml) 3. Place the beaker on the hot plate with the hot plate TURNED OFF. 4. egress two temperature measurements of the deoxyephedrine/ piss slurry 30 seconds apart. 5. Do not let go of the thermometer. 6. Do not let the thermometer cope with the beakers sides or bottom. 7. while the hot plate on to about 6 (about halfway). 8. put in temperature measurements every 30 seconds.The plateaus were not altogether flat and fluctuated between 2 degrees of temperature. We didnt get to record measurements later reaching 100 co because we ran out of time and our outlet wasnt working. Anal ysis 2. grade changes are possibility to the water during the flat areas of the graph. 3. The water is high temperature up during the slanting areas of the graph. 4. More than one phase of water is present in the flat areas of the graph. 5. The wake up from the hot late is converted to verve when the water is changing from icing the puck to liquid. 6.The heat from the hot plate is changing the temperature of the water when it is only liquid. 7. The graph would have a slower change in temperature over time if we had double the amount of water, so the graph would be agelong horizontally. My guessing was confirmed because our info that showed minuscule displace temperatures for the plateaus and the rise/ limit in temperature for the slopes. However, I had not signly accounted for the slight slash of temperature in the outgrowth due to the ice lolling the water because the water was room temperature.I versed that plateau points on the graph do not expect only one tempe rature but quite fluctuate. We did have a possible bank of error due to possible wide temperature readings, not take temperature readings, inconsistent time, and not exact time intervals. If we do this taste again, we can puree changing the temperature of the initial water added or the amount of water added to see if we experience any perceptible differences. Watching water supply change phases took longer than I though
