The graph is very important.

B. Volume-Temperature Data for Gases Prepare a graph using the following data for a 100mg sample of nitrogen gas at constant pressure, as temperature increases. 1. Which is the independent variable? Plot this along the horizontal (x) axis. Which is the dependent variable? This should be graphed along the vertical ( y ) axis. 2. For this graph, you will need to determine the intercept. This is the value along the vertical ( y ) axis where the value of the x-axis equals zero. Because you need to determine the intercept, scale the x-axis so that it begins at zero. The vertical (y) axis does not need to start at zero. Scale each axis so that the data fills most of the graph. Label each axis with the appropriate information including units, and have values spaced every 5 or 10 lines. Write the appropriate title at the top of the graph including any relevant information. 3. Plot the data by making a small mark for each point. 4. If the data is linear, use a see-through straight edge or ruler to draw the straight line that best represents the data. The line may not go through all the points. Using a dotted line, extend the line past the data to the intercept, where the line intersects with the vertical (y) axis. Determine the value of the intercept and clearly indicate the intercept and its value on the graph. 5. Calculate the slope of the line. Choose two points on the line that are on the corners of the grid, and far apart. Do not use data points to calculate the slope
