Thepurpose of this lab was to see the relationship of temperature and volume.During this experiment I proved Charles’s law to be right. Charles’ law states that temperature andvolume of a gas are proportional to each other, so whenthe absolute temperature increase, the volume increases. And when the absolutetemperature decreases so does the volume. Conclusion Mycalculates values were a little off than my experiment values.
However, you canprove Charles’s law to be right no matter if you used my calculated results ormy experimental results. In this experiment whenever my volume increase, so didthe temperature. And when the volume decreased, the temperature decreased aswell. Sofor trial A, I used (V1 and T1) 20/293.15 and got 68 asmy answer. For trial B, I used (V1 and T2) 17/253.15 andthe answer was 67.8.
These are proportional to one another. I than completedthis formula for the rest of my trials and discovered that the near equality innumbers can be attributed to Charles’s Law. Charles’s law states when the absolutetemperature increase, the volume increases.
And when the absolute temperaturedecreases so does the volume. Inthe experiment the temperature and the volume worked together. To prove thatCharles law is correct I used the formula below.

Next, I added a thermometer. I than added200 ml of distilled room temperature water to the beaker. I than placed the Bunsen burner underneath the beaker and let the water reach 100° Celsius. I removed the Bunsen burner. Next, I placed the syringe into the beaker and allowed for the temperature in the syringe to reach the same temperature as the water in the beaker. I lastly, recorded the volume and temperature TrialE: I removed the syringe from the water bath and emptied the beaker.
Next, I added a thermometer. I than added 100ml of distilled room temperature water to the beaker. Then, I selected a Bunsen burner and placed it underneath the water. I let the beaker heat up until the water reaches 100° Celsius. Next, I added 100 ml of distilled room temperature water to the beaker.
I than removed the Bunsen burner. Next, I placed the syringe into the beaker. And allowed for the temperature in the syringe to reach the same temperature as the water in the beaker. I than recorded the volume and temperature.
TrialD: I removed the syringe from the water and emptied the beaker. I than added a thermometer. I than added 100ml of distilled ice water to the beaker.
Next, I added 100 ml of room temperature water to the beaker. I than record the temperature. I than placed the syringe, into the beaker. And allowed the temperature of the syringe to reach the same temperature as the water in the beaker. And then, I recorded the volume and temperature.TrialC: I selected a 250ml beaker. I added 200ml of distilled ice water to the beaker.
I thank added a thermometer. I than selected the syringe and placed it into the beaker I waited and allowed for the temperature in the syringe to reach the same temperature as the ice water bath (-20° Celsius). I recorded the volume and temperature.TrialB: I recorded the volume and temperature. TrialA: I first selected the gas syringe sealed. I than set the syringe volume to 20ML. I than added a thermometer to the syringe.
InitialSetup: Procedure Thislab is designed to apply the Charles’s law by experimenting what happens whendistill water is mixed with room temperature water or ice water. I observed whether volume is lower than the temperature,higher than the temperature or if the volume is proportional to thetemperature. I observed that throughout the experiment that the volume stayedproportional to the temperature. Introduction
