3. Think of a bag of cake flour. You can pour the cake flour out of the bag and into a mixing bowl. Does this mean the flour is a liquid? Explain whether you think the cake flour (and all powders) are solids or liquids.
The cake flour is not a liquid, but a solid. Flour, and all powders, are solids made of very fine grains which are able to flow freely when they container is tilted or shaken. But these grains are solid.
liquids have freely moving atoms that take availabke space when poured into something. the flour may be freely moving and the flour may change to fit the container, but, the individual flour particles are not liquid.
