Volume is a measure of the amount of space an object takes up. It is always in three dimensions. To find the volume of an objects like a cube or a box, measure the length × width × height. If measured ...

Plot a graph of mass in g on the y-axis against volume in cm 3 on the x-axis. Draw a line of best fit through the points. The gradient of the graph = \(\frac{mass}{volume}\) = density of water.

In the animation, you saw that as water is cooled the water level goes down. Cold water has a smaller volume, but the mass stays the same. What does this tell you about the density of cold water?

"We want a good amount of volume, and that volume ideally should be made up of fiber and water content," Fonnesbeck said. "It has to be in foods; it doesn't work to drink water and take fiber ...
