Answer:

Only temperature

Explanation:

The information provided in a graph is flow rate and temperature. This graph is flow rate verses temperature. Temperature is plotted on x- axis and flow rate on y axis.

According to rules for plotting  a graph:

  • x-axis shows independent variable
  • y-axis shows the variable dependent on x-axis

Thus, here flow rate changes according to change in temperature. So, temperature is independent variable and flow rate is dependent variable.

Answer: Only Temperature

Whenever, variables are plotted on a graph, the independent variables are plotted on x-axis and the dependent ones on the y-axis. The graph is formed, when the dependent variable is plotted against the independent one.

Here, in the given graph, temperature is plotted on the x-axis and flow rate on y-axis. Hence, only temperature is the independent variable. Also, flow rate depends on the temperature of the substance and not the other way round.
