Step 1
Plot the Results
Answer
-
Start by identifying the points from the data:
- (0, 0)
- (1, 52)
- (2, 78)
- (3, 91)
- (4, 97)
- (5, 100)
- (6, 100)
-
Using the provided graph, accurately mark each point corresponding to the time in minutes on the x-axis and volume of gas in cm³ on the y-axis.
-
After plotting the points, connect them with a smooth line to create a curve of best fit, ensuring to capture the trend of gas volume increasing over time.
