Date – 11/23 Lab Day – Lab Start Time – 11:00 Act B4 Properties and Relationships of Gases Lab Report During the lab you collected both qualitative and quantitative data on the properties of a gas. In the following you will examine the data you collected during the lab and complete an analysis. PART I: The Relationship between Temperature and Volume in an Ideal Gas Simulation Using the Phet Gas Properties simulation, you collected data to explore the relationship between temperature and volume in an ideal gas. You moved slider to change its temperature. 1. Two variables are held constant in this experiment. Identify them. Briefly explain how you know that these are the controlled variables. Variable 1: Amount of Gas Variable 2: Pressure 2. Construct a scatterplot for all the data in Act B4 Part I with Collisions in 10 ns as the independent variable and Pressure in atm as the dependent variable. Paste your Excel graph below. 0 10 20 30 40 50 60 0 1 2 3 4 5 6 7 Relationships Between the Pressure and the Number of collisions 3. Which term best describes the relationship between the number of collisions per 10 ns and pressure in atm, direct, inverse, constant or independent? Briefly explain how the data indicates the term you selected. There is a steady correlation between pressure and the number of collisions every 10 ps. According to the graph of the class data, pressure does not change as the number of collisions per 10 ps rises. There is a continuous pattern of straight lines on the horizontall axis of the graph. 4. Use the Act B4 Class Data File for Part I to construct a scatterplot with the Temperature (K) as the independent variable and Volume-Width (nm) as the dependent variable. Paste your Excel graph below. 1

Which term best describes the relationship between temperature and volume of an ideal gas, direct, inverse, constant or independent? Briefly explain how the data indicates the term you selected. An perfect gas has a straight proportionality between its temperature and volume. A gas's volume grows in proportion to its temperature, according to the class data. 6. Identify the gas law that corresponds to these data. Charles' law on volume and temperature applies to this data. It asserts that, under certain conditions, a gas's volume grows proportionately to its temperature, provided that its pressure and mass remain constant. 7. Use your graph to predict the volume- width (nm) that the gas will occupy if the temperature is 100 K. You may indicate your prediction on the graph or show a calculation. Based on the graph that I constructed with a linear trendline, at about 100 K, the volume-width would be about 15.0 nm. 2

PART II : The Relationship between Pressure and Volume in an Ideal Gas Simulation Using the Phet Gas Properties simulation, you collected data to explore the relationship between volume and presssure in an ideal gas. You moved the handle on the container of gas to change its volume. 8. Two variables are held constant in this experiment. Identify them. Briefly explain how you know that these are the controlled variables. Variable 1: Amount of Gas Variable 2: Temperature 9. Construct a scatterplot for all the data in Act B4 Part II with Volume-Width(nm) as the independent variable and Pressure in atm as the dependent variable. Paste your Excel graph below. 4.0 6.0 8.0 10.0 12.0 14.0 16.0 0.0 2.0 4.0 6.0 8.0 10.0 12.0 14.0 Relationship Between Volume (nm) and Pressure of a Real Gas (atm) (x, volume, y, pressure) 10. Use the graph to describe how the pressure changes if the volume-width (nm) increases or decreases. Is the plot linear? The graph illustrates how these two variables are inversely related: when the volume-width drops, a gas's pressure increases. The plot appears to be a falling exponential graph rather than a linear one. 11. Construct a scatterplot for all the data in Act B4 Part II with the reciprocal of Volume-Width (nm) or 1/Volume- Width(nm) as the independent variable and Pressure in atm as the dependent variable. Paste your Excel graph below. 3
