Ideal Gas Lab Report - Alternative Template

Ideal Gas Lab Report - Alternative Template Instructions: For this investigative phenomenon, you will need to determine the relationship between volume and temperature of real gases. Record your data and calculations in the lab report below. You will submit your completed report. . Title: Ideal Gas lab Objective(s):Examine the relationship between the volume and temperature of a gas using gasses sealed inside syringes Hypothesis: If I place the syringe in higher temperature water baths then their volume will increase. Procedure: This lab already includes materials and a summary of steps to follow. List and explain your controlled variables, independent variable and dependent variable for this lab in the table provided below. Materials: Ideal Gas Virtual Lab Variables: Remember, controlled variables are factors that remain the same throughout the experiment. An independent (test) variable changes so that the experimenter can see the effect on other variables. The dependent (outcome) variable will change in response to the test variable. Variables of for this lab Independent Variable temperature of the water, and type of gas Dependent Variable volume of the gas Controlled Variables Amount of gas in syringe Summary of Steps: 1. Fill a 10 mL syringe half full with air. 2. Fill a second 10 mL syringe half full with one of the following gases ( N2 or H2 or He). 3. Place each syringe in a bath of ice and saltwater, measure the temperature of the water with a thermometer and the volume of the syringes and record the data in the table below. 4. Repeat steps 1-3 for each of the following changes in temperature: Ice water, Room temperature water, Warm water, Hot water. Data: Complete the table to organize the data collected in this lab of both Air and your gas of choice. Don’t forget to record measurements with the correct number of significant figures. Volume (mL) Temp (⁰C) Air Volume (mL) Air Ice and saltwater -14.5 4.40 -14.7 4.25 Ice water 0.50 4.60 0.80 4.60 Room temp water 21.8 5.19 21.4 5.20 Warm water 48.8 5.44 48.2 5.40 Hot water 80.8 5.88 81.1 5.80 Water Bath Temp(⁰C) Nitrogen Pick one: N2 Analysis: Create a separate graph of temperature vs. volume for your gas sample. You are encouraged to use graphing software or online tools to create the graphs; be sure to take screenshots of the graphs that also include your data. Make sure to include the following on your graphs: • • • Title Labels for axes and appropriate scales Clearly plotted data points Sample Graph Templates: Desmos Template (click here) or Google Sheet - Graph Template (click here) Graph of Air Calculations: 1. If the atmospheric pressure in the laboratory is 1.2 atm, how many moles of gas were in the air and your choice of gas syringe? I got 0.72 I used the formula on the help template I used the gas nitrogen and the values -14.7 and 4.25 Conclusion: Write a conclusion paragraph that answers the following questions: ● Does your data support or fail to support your hypothesis (include examples)? My data supports my hypothesis because as we increase the temperature of the water both volumes of the gasses increase in temperature such as when the water was 0.80 degrees celsius the volume of the gas was 4.60 and when we increased the temperature of the water to 21.4 degrees celsius the volume of nitrogen went to 5.20. ● Discuss any possible sources of error that could have impacted the results of this lab. Maybe the thermometers could have been old or just overall the equipment being old to measure certain temperatures and things. ● Which gas law is this experiment investigating and how does your graph represent this gas law? The ideal gas law is being represented here by the graph because the gas is held constant and while temperature is increased the pressure will also increase. ● Using your knowledge of the kinetic molecular theory (KMT) of gases, describe the relationship between volume and temperature of an ideal gas based on your data observations. When pressure remains constant, volume increases as temperature rises. As shown in the graph, the volume of each gas increasest as the temperature rises. ● How do you think the investigation can be explored further? Think about the other variables in the ideal gas law (PV=nRT). We could experiment with different independent variables and dependent variables like instead of water we can use a different liquid and for the dependent variable we can find the volume of instead of a gas something else.
