The density of a substance is the ratio of its mass to its volume. It is always necessary to state the units of density because it may be expressed in a number of different mass and volume units.

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.

{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.

Even with comparatively low temperatures (e.g. a few eV), plasmas formed at high density have a high energy content per unit volume and form a subset of the research field of high-energy density ...
