Question

looking at the graph, what is the independent variable? vapour pressure volume temperature

Explanation:

In a graph, the independent variable is typically plotted on the x - axis. Here, the x - axis is labeled "Temperature (°C)", and the y - axis is labeled "Vapour Pressure, Torr". The independent variable is the one that is manipulated or is the cause, and the dependent variable (vapour pressure here) depends on it. Volume is not plotted on either axis. So the independent variable is Temperature.

Answer:

Temperature
