{volume}\) = density of water. Calculate the gradient of the graph and hence the density of water. As for the previous experiment, the line of best fit is a straight line through the origin.

The Control Variables are what we keep the same during the experiment to make sure it’s a fair test. Independent Variable is the volume of the object. Dependent Variable is the mass of the object.

The physical properties of seawater include both 'thermodynamic properties' like density and freezing point ... These physical properties include the volume-to-mass ratio of a solid, liquid ...
