What are the variables of the graph shown to the right? Describe how the variables are related at various points on the graph.
What are the variables of the graph?
Time and Air in Balloon
Volume and Time
Air in Balloon and Volume
The variables of the graph are Air in Balloon and Volume.
At various points on the graph, the variables are related as follows:
- As time increases, the volume of the balloon increases. This indicates that more air is being pumped into the balloon over time.
- As time decreases, the volume of the balloon decreases. This suggests that air is being released from the balloon over time.
- The relationship between air in the balloon and volume is directly proportional. As more air is pumped into the balloon, the volume increases, and as air is released from the balloon, the volume decreases. This indicates that the amount of air in the balloon directly affects its volume.
