Explain the value of the slope

The slope of a graph with volume ($V$) on the vertical axis and time ($t$) on the horizontal axis represents the rate of change of volume over time. In this context, the value of the slope, $0.175 \text{ cm}^3/\text{s}$, indicates the flow rate at which the volume is increasing. This means that for every second that passes, the volume increases by $0.175 \text{ cm}^3$.
