Using data from the figure, graph the density as a function of the temperature for liquid water from 100°C to 4°C.

Question

Answer 1

So the best way to answer this question is to create a table of x and y values which can be read from the above graphic.

Set X = Temperature (°C)

Y = Density (g/cm³)

So your table looks like

X (Temperature) Y(Density)

4 1.000

10 0.9997

25 0.9971

50 0.9881

100 0.9584.

Now plot the graph:

1. Ensure the X-axis is Labelled Temperature (°C)
2. Ensure the Y-axis is labelled Density (g/cm³)
3. Plot only from 4 to 100 °C as the question asks.
4. The question doesn't ask for the gradient or y-intercept

Hope this helps!
